Sauce documentation updated for the 23 to 25 September releases. The Sauce pages now follow
@eco-incorp/sauce 0.99.4 (Node 24, compiler 2.3.0): the Sauce SDK quickstart and Getting started build an intent with Base(body, options).reward(...), prepare the Executor-owned Pot and Kitchen fee, and fund it; Programs as intents covers intent options, token and protocol globals, builders and nested intents; Architecture and deployments lists the execution fee, compiler and engine pins, and the release addresses on 16 EVM mainnets and Solana mainnet. The SDK reference is regenerated from 0.99.4 and the compiler API from 2.3.0. The local dev-tools page was removed: the package documents that scaffold as incompatible with current Kitchen and Pot deployments.Docs
Intent types reference. Intent types names the route shapes a quote can contain (Eco solver fill, post-bridge swap, pre-bridge swap, third-party routing over Circle CCTP, same-chain swap), with a live response, a sequence diagram and the status view for each, and is linked from the quote, status and verification pages.SDK reference, Cookbook and Resources. A new SDK reference tab documents every export of
@eco-incorp/sauce 0.99.1 and @eco-incorp/sauce-compiler 2.2.1 from their type declarations. A Cookbook tab collects the end-to-end guides and the complete Sauce programs shipped in the packages. Resources gains an FAQ, Security and audits, Support and community, and separate changelogs for the API and the Sauce SDK.Docs
Sauce documentation rebuilt from sauce.eco.com and the published packages. Program your route and the Sauce SDK now describe Sauce as shipped: a Turing-complete runtime for the EVM and SVM (closed access),
@eco-incorp/sauce-compiler 2.2.1 and @eco-incorp/sauce 0.99.1. New pages: Getting started, SauceScript reference, Examples, Programs as intents, and Architecture and deployments with the v1.0.0 addresses. An eco-sauce agent skill ships alongside.Capabilities renamed to what you do with them. Following the product map (v4.3), capability pages and sidebar sections now carry the verbed labels: Send & Swap across chains, Deposit & Payout, Program your route, Enable 1:1 stablecoin UX, Ensure end-to-end compliance. The engines keep their names in the first sentence of each page and in contracts and API paths (Routes, Programmable Addresses, Programmable Transactions, Verified Liquidity). Added a Routes API + CLI landing page under Core, and renamed the persona section to Who uses Eco.API
Eco API v1 reference. The API reference now documents
https://api.eco.com/v1: chains and tokens discovery, signed quotes with a ready-to-send execution.transaction, gasless funding with Permit3, Permit2 and ERC-3009, intent status, and the Circle Gateway deposit-address endpoints under /v1/circle-gateway/. Every v1 endpoint except Circle Gateway takes an x-api-key. Quotes carry an EIP-712 signature; see Quote verification. The legacy quotes.eco.com exact-input endpoint stays available as the keyless Open quoting service.Integration guides on v1. Integrate the Routes API, Sending USDC across chains, Treasury rebalancing and the Circle Gateway pages now use the v1 endpoints and shapes (type, source.funder, dappId, destination.amountOut).Skills. eco-api-v1 replaces the earlier Routes API skill and ships with transfer.ts, a reference script that quotes, verifies, funds and tracks a transfer from an EVM or Solana source chain. See Agent integration.Docs
Navigation redesign. The docs now follow the platform map: a linear Get started path (Welcome, Platform overview, Get set up, first transfer, Routes API integration, agents), then What we support, Who we serve, and Guides by common use case. A Developer platform tab groups products by pillar: Routing, Deposits, Programmability, Compliance, plus Core concepts and Protocol architecture. Changelog is its own tab. Product tabs for Routes, Programmable Addresses, Programmable Transactions and Verified Liquidity became pillar sections; old links redirect.Custom agent skills. Skills now ship from the docs repo and are served at
/.well-known/skills/: the Eco API v1, Deposit & Payout addresses, and becoming a solver.Coverage
Delisted chains that are no longer enabled from Supported chains and tokens and removed the Crowd Liquidity pages. Old Crowd Liquidity links redirect to the Routes overview.
Smart Deposit Addresses
Added a testnet guide for Circle Gateway Fast Deposits: send testnet USDC on Base Sepolia, OP Sepolia or Arbitrum Sepolia and receive a Gateway balance on Polygon Amoy.
Cross-Chain Swaps & Transfers
Documented Flash Intents, the same-chain mode that fills orders from the user’s own vaulted funds via
flashFulfill, and the any-token swap quote endpoint on api.eco.com.Smart Deposit Addresses
Restored Solana Deposit Addresses (a deterministic EVM address on Base that auto-routes USDC to a Solana wallet) and replaced generated diagrams with Eco-branded architecture diagrams across the Routes pages.
API
Circle Gateway Deposits moved to the quoted-vault scheme:
POST /circle-gateway/v2/depositAddresses on https://api.eco.com returns a per-intent vault with a quote deadline. EIP-2612 Permit is a supported funding method alongside ERC-3009 and direct transfer. See Funding methods.Compliant Liquidity
Renamed Institutional Liquidity to Verified Liquidity, a closed-access offering. Contact Eco for current onboarding and integration requirements.
