Product names and capabilities. The core developer tools are Routes API + CLI and Sauce SDK. Home uses Program your route for the programmability capability. The new Developer platform overview maps application outcomes to products and tools, including standalone payments, swaps, lending and conditional programs.Quickstarts in one place. The Quickstarts tab contains Routes, deposit and solver walkthroughs, plus a dedicated Sauce SDK section for the first program and all former cookbook examples. The Sauce SDK tab contains tool guides, language and runtime documentation, and references. Moved pages have redirects, and product and use-case pages link to the canonical walkthroughs. Legacy section URLs have catch-all redirects to current section landings; package reference pages now live under
/sauce-sdk.A clearer learning path. Get started separates understanding Eco, choosing an integration and setting up. Overview pages introduce unfamiliar terms before using them, while orchestration explains the broader funding, execution and tracking flow. Programs, destination calls and cross-chain settlement retain their distinct execution boundaries.Docs
Sauce tab. The SDK reference tab is now Sauce. At that release, its sidebar grouped the Sauce language reference (SauceScript, V12, the Kitchen, the Pot, bytecode and
cook()); the Sauce SDK: installation, the sauce command, the MCP server, the agent skills, the TypeScript library, and the generated chain, protocol, token and deployment references; a Sauce cookbook of complete programs with the commands that run them; the @sauce/token and @sauce/router library pages; and the package references for @eco-incorp/sauce and @eco-incorp/sauce-compiler. The Programmable Transactions pages under Program your route are now short product pages that link into the Sauce tab for detail.Tab renames and redirects. The API reference tab is now Routes API (/routes-api/*), and the Cookbook tab is now Quickstart (/quickstarts/*). The Cookbook’s Sauce programs moved to the Sauce cookbook. Old URLs redirect to the pages that replace them.Install-first layout at that release. Home, the Get started pages, the Developer platform’s Sauce SDK page, the Sauce and Sauce SDK introductions and the cookbook overviews started with installing the sauce command (npm install -g @eco-incorp/sauce) and adding the Sauce MCP server to your coding agent (sauce mcp setup).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.

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.
