You are integrating the **Ryze offline quote SDK** (Go binding) into this repository so it can compute Ryze AMM **single-asset join quotes** locally — no HTTP call, no RPC, no network at all. Study the repo first and match its conventions (module layout, config handling, error types, logging, test framework). If you are instead running in an empty directory, create a minimal standalone module (run `go mod init verify-ryze` first — the wiring commands below edit an existing go.mod) whose only purpose is the verification script defined at the end — the acceptance gate is identical either way. ## What the SDK is The Ryze quote SDK is a precompiled native library (`libryzesdk`) plus a thin Go binding. It reproduces the exact quote math of the on-chain Ryze AMM (an oracle-anchored weighted-pool DEX on Base): same integers, same rounding, same errors. You hand it a snapshot of a pool's state; it returns the quote synchronously, in microseconds, with zero I/O. This replaces quoting through Ryze's hosted Router API on the hot path — same numbers, none of the latency. It is distributed as a platform tarball: `ryze-sdk-go--.tar.gz` (darwin-arm64, linux-amd64, …). Obtain the tarball matching your deploy target from the Ryze team. Throughout this prompt `$RYZE_SDK_DIST` means the absolute path of the UNPACKED distribution folder — read it from the environment; never hardcode it (single exception: the `replace` path in go.mod, as documented above). ## Distribution layout & wiring ```text $RYZE_SDK_DIST/ go.mod # module github.com/ryze-protocol/ryze-sdk-go (go 1.22) ryze.go # the binding: package ryzesdk (cgo) include/ryze_sdk.h # C header consumed by the binding lib/libryzesdk.* # the closed-source native quote engine (.dylib/.so/.dll) example/quote.go # smoke example ``` **Wiring.** Point your module at the unpacked folder (substitute the actual value of `$RYZE_SDK_DIST` — this is the one place an absolute path is acceptable): ```bash go mod edit -require=github.com/ryze-protocol/ryze-sdk-go@v0.0.0 go mod edit -replace=github.com/ryze-protocol/ryze-sdk-go=$RYZE_SDK_DIST go mod tidy ``` ```go import ryzesdk "github.com/ryze-protocol/ryze-sdk-go" ``` - **cgo is required**: build with `CGO_ENABLED=1` and a C toolchain installed. - The binding bakes an rpath to its own `lib/` dir (via `${SRCDIR}`), so no runtime env vars are needed as long as the distribution folder stays intact. Do not move or rename files inside it. - Calls are **synchronous**; failures return an ordinary `error` whose text is the engine's error message. - The request structs' `WBRConfig` field is `any` — pass a `json.RawMessage` holding the verbatim config object. ## The API you are integrating ```go import ryzesdk "github.com/ryze-protocol/ryze-sdk-go" resp, err := ryzesdk.QuoteSingleAssetJoin(ryzesdk.SingleJoinRequest{ ... }) // sync type SingleJoinRequest struct { Pool WeightedPool TokenIn string // the single token being deposited AmountIn string // base units of TokenIn IsIntentSwap bool // price with discounted intent fee rates FeeMultiplierWad string // per-account fee discount (wad); "" for full fees TokenPrices []TokenPrice // REQUIRED for SmartShield pools WBRConfig any // REQUIRED for SmartShield pools; pass json.RawMessage } type SingleJoinResponse struct { AmountIn string // echo of the deposit PoolSharesOut string // LP tokens minted (18 decimals) PoolAddress string // lowercase TVL string // pool TVL in USD, wad (1e18 = $1) FeeDetails FeeDetails // fees charged in TokenIn; WbrFee in the other pool token } ``` All binding types are declared in the distribution's `ryze.go` with camelCase JSON tags — the fixture below unmarshals directly into them. ## Non-negotiable semantics - Every amount, balance, weight, fee, and price is a **base-10 integer string** in base units. Never let a float touch any of these values — not in parsing, not in display math inside the quote path. - "Wad" fields are 18-decimal fixed point: 1e18 = 1.0 (= 100% for rates/weights). - `pool` is a point-in-time snapshot. In production hydrate it from the Ryze API (`GET {RYZE_API_URL}/pools` — mainnet `https://mainnet.api.ryze.pro/api`, testnet `https://sepolia.api.ryze.pro/api`) or your own indexer, and re-quote when state changes. The SDK is deterministic: stale input means stale quote. The verification script below uses the embedded fixture INSTEAD of any network fetch. - `pool.assets` order is canonical — preserve it in every array you build. - SmartShield pools (`smartShieldEnabled: true` — the fixture pool is one) price against the oracle. For them BOTH `tokenPrices` AND `wbrConfig` are REQUIRED and travel together: omitting `tokenPrices` fails with `InvalidPriceData()`; supplying prices but omitting `wbrConfig` fails with `WeightBreakingRewardError("Config not loaded")`. Pass `wbrConfig` through VERBATIM as one opaque JSON object, exactly as the Ryze API returns it — never interpret, rename, filter, or re-derive its fields. - `tokenPrices` are USD per WHOLE token in wad (1e18 = $1.00) — e.g. the fixture prices USDC at $0.9997 and WETH at $1662.50. - Responses echo all addresses in **lowercase**. Compare addresses case-insensitively everywhere. - Engine errors are terse Solidity-style strings (`InvalidSlippage()`, `WeightedPoolMathError("...")`). Treat them as opaque: assert on them in tests, never branch on them in production logic. - A single-asset join is priced like a partial swap into the pool's other side, so it pays swap-type fees (that is why the response carries `feeDetails` and a proportional join does not). - `tvl` is the pool's total value locked in USD wad (1e18 = $1) under the supplied oracle prices — useful for share-price sanity checks upstream. ## Deliverable 1 — the integration module Expose one narrow, typed function — for example `quoteRyzeSingleJoin(pool, tokenIn, amountIn, opts)` — returning the LP shares minted, the pool TVL, and the fee breakdown — where `opts` carries the pass-through inputs (`isIntentSwap`, `feeMultiplierWad`, `tokenPrices`, `wbrConfig`; the last two are required for SmartShield pools). Internally it must do nothing but validate inputs, assemble the SDK request, call the SDK, and map the response into your codebase's own types. Do NOT post-process the numbers: no rounding, no fee re-derivation, no float conversion — the SDK's integers are the on-chain truth. Example names above are illustrative — adapt them to this language's and this repo's conventions (snake_case in Rust, exported PascalCase in Go, camelCase in TypeScript). ## Deliverable 2 — standalone verification script (the acceptance gate) Create `cmd/verify-ryze-join-single/main.go` (repo mode) or `main.go` of a fresh module (standalone mode); run with `go run`. The script must be fully self-contained: it embeds the fixture below verbatim, calls the SDK through YOUR integration module (not around it), checks every assertion in the table, prints one `PASS ` / `FAIL expected= got=` line per assertion (a table row that bundles several fields may emit one line per field), and exits 0 only if every assertion passed. For the negative case: check the returned `error`'s text. Golden values below were produced by this exact SDK build from this exact fixture — they are deterministic. An off-by-one is a real failure; investigate your request construction before suspecting the goldens. ### Fixture (embed verbatim — tokens are USDC, 6 decimals, and WETH, 18 decimals) ```json { "pool": { "address": "0x0000000000000000000000000000000000001001", "totalSupplyLP": "1000000000000000000000", "parameters": { "swapFeeWad": "1000000000000000", "takerFeeWad": "500000000000000", "smartShieldEnabled": true, "smartShieldParams": { "thresholdWeightDiffWad": "10000000000000000", "minOracleWeightWad": "150000000000000000" }, "intentSwapFeeWad": "400000000000000", "intentTakerFeeWad": "200000000000000" }, "assets": [ { "tokenAddress": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "balance": "1000000000000", "weight": "500000000000000000", "decimals": 6, "liability": "0", "custody": "0", "externalLiquidityRatio": "2000000000000000000", "liquidityBands": [ { "thresholdWad": "1000000000000000000000", "ratioWad": "2000000000000000000", "minSlippageWad": "100000000000000" }, { "thresholdWad": "100000000000000000000000", "ratioWad": "1500000000000000000", "minSlippageWad": "200000000000000" }, { "thresholdWad": "1000000000000000000000000", "ratioWad": "1200000000000000000", "minSlippageWad": "400000000000000" } ] }, { "tokenAddress": "0x4200000000000000000000000000000000000006", "balance": "500000000000000000000", "weight": "500000000000000000", "decimals": 18, "liability": "0", "custody": "0", "externalLiquidityRatio": "2000000000000000000", "liquidityBands": [ { "thresholdWad": "1000000000000000000000", "ratioWad": "2000000000000000000", "minSlippageWad": "100000000000000" }, { "thresholdWad": "100000000000000000000000", "ratioWad": "1500000000000000000", "minSlippageWad": "200000000000000" }, { "thresholdWad": "1000000000000000000000000", "ratioWad": "1200000000000000000", "minSlippageWad": "400000000000000" } ] } ] }, "tokenPrices": [ { "token": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "priceWad": "999700000000000000" }, { "token": "0x4200000000000000000000000000000000000006", "priceWad": "1662500000000000000000" } ], "wbrConfig": { "wad": "1000000000000000000", "maxWbfWad": "990000000000000000", "maxExpArgWad": "20000000000000000000", "maxFeeBps": "10000", "maxSkewPenaltyWad": "40000000000000000", "maxWbfRateBps": "400", "maxWeightWad": "1000000000000000000", "weightThresholdWad": "550000000000000000", "weightThresholdLambdaWad": "600000000000000000", "weightThresholdLogWad": "800000000000000000", "weightThresholdSigmaWad": "550000000000000000", "weightMultiplierLogWad": "10000000000000000000", "weightHalfWad": "500000000000000000", "bQuoteAdjustmentWad": "0", "bOverflowCap": "1000000000000000000000000000000", "bSAnchorS": [ "250000000000000000000", "1000000000000000000000", "10000000000000000000000", "100000000000000000000000", "500000000000000000000000", "1000000000000000000000000", "2500000000000000000000000", "5000000000000000000000000" ], "bSAnchorBpsWad": [ "0", "2000000000000000000", "3000000000000000000", "6000000000000000000", "11000000000000000000", "15000000000000000000", "25000000000000000000", "45000000000000000000" ], "bSNumAnchors": "8", "fPowMultiplier": "5", "fPowExponentWad": "2500000000000000000", "fLogExponentMultiplier": "10", "fLogOverflowDivisor": "10", "smoothstepCoeff1": "3000000000000000000", "smoothstepCoeff2": "2000000000000000000", "wrrDivisor": "2", "wrrMaxBps": "200", "wrrWeightMaxWad": "850000000000000000", "basisPointsDivisor": "10000", "bpsToWadMultiplier": "100000000000000" } } ``` ### Assertions | # | Call | Expected (assert EXACTLY) | |---|---|---| | 1 | `tokenIn`=USDC, `amountIn`="1000000000", with fixture `tokenPrices`+`wbrConfig` | `poolSharesOut` = "545545661580042036" | | 2 | same response | `tvl` = "1830950000000000000000000" | | 3 | same response | `feeDetails`: swapFee.amount="453999", takerFee.amount="226999", wbfFee.amount="39058", slippageFee.amount="113472" (all in USDC) | | 4 | same response | `amountIn` echoed = "1000000000";

no silent re-rounding of SDK outputs. - Do not modify, move, or rename anything inside `$RYZE_SDK_DIST`. - Do not reimplement or "simplify" the quote math from observed outputs — the SDK is the only source of Ryze numbers in this codebase. - Keep the wbrConfig object opaque wherever it appears. ## Acceptance checklist (verify each before declaring done) - [ ] SDK wired via `$RYZE_SDK_DIST` (only go.mod may contain the literal SDK path) - [ ] Integration module exposes the typed function(s) described above, in this repo's own conventions - [ ] Verification script exists, runs offline, prints one PASS/FAIL line per assertion, and exits 0 with every assertion passing - [ ] All amounts handled as integer strings end-to-end - [ ] The negative test asserts the failure, i.e. a successful quote there is a FAIL - [ ] You actually RAN the verification script and pasted its output in your summary
