Blockchains and stablecoins promised us programmable money. So far we have smart contracts, but dumb transactions. Today, Eco is launching the Sauce SDK and Skills to upgrade the transaction itself: turn onchain transactions into programs with guaranteed outcomes, across EVM chains and Solana. Your logic runs inside the transaction, against live market conditions, and delivers the outcome you defined or reverts entirely. Built for developers, agents, and enterprises moving money onchain. Live on @Arc, @Base, @Ethereum, and @Solana today (with more to come). Eco was built to deliver on the promise of programmable money. Sauce takes that mission a big step further by giving you more control, with failsafe execution. Read more below, or visit eco.com/sauce to get started.

.@Paxos-issued $USDG @global_dollar supply on @arbitrum has grown 5x this month. ↳ $USDG held in @Morpho went from $0 to $42.6M ↳ $USDG held in @GMX_IO went from $0 to $13.7M Data: @EntropyAdvisors

Each new chain a stablecoin launches on adds users, and one more place its liquidity has to be found. @alexlimasia, Head of APAC at @LayerZero_Core, on what that growth requires.

Create a @Circle Gateway deposit address, collect an ERC-3009 signature, and track funding and delivery. Use ERC-3009 when a user holds $USDC, but does not hold the source chain’s gas token. The user signs a transfer authorization; Eco’s service submits it onchain. Gasless funding removes the user’s source-chain gas transaction, but it does not imply that a quote has no fees.

.@arc has cleared $18.71B in stablecoin transfer volume since mainnet opened five weeks ago. ↳ Stablecoin supply on the chain sits at $897M, its highest since launch and 68% above the late-September low ↳ Every dollar of that supply has turned over more than 20 times in five weeks Eco has been live on Arc since mainnet opened, building one integration that connects the chain to where the rest of the market’s dollars sit.

Integrating Eco meant learning the quotes service and the solver endpoints separately, each with its own request shape. The new Eco API puts quoting, funding, routing, and transaction status behind one base URL, with one key and one error catalog. Learn more in the blog below:

Where are your stablecoins while a transfer is still in flight? @strao_, Head of Product at Eco, on what a treasury team should be able to point at.

Move stablecoins with one API. The new Eco API puts everything you need for stablecoin swaps and transfers in one place. Built for developers. One key, one request shape, one error catalog. Every quote is signed, so you verify it before funds move. End users get clear status updates, whatever you’re building. Read the blog post:

Programmable Addresses V2 is live! Accept deposits from whatever chain and stablecoin your users already hold, with one API call for you and one transfer for them. V2 gets every deposit the best price available at that moment, shows your user the exact cost before they send, and lands the funds exactly where you want them. Every deposit reconciles automatically. Learn more:

.@Rhinestonewtf now gives any app a single stablecoin balance that works across all chains, powered by Eco. Rhinestone provides a self-custodial account, and Eco routes stablecoins through it, moving any major stablecoin across any supported chain in seconds. Users sign once, and their money is where they need it. Want stablecoin routing for your own product? Check out Eco Routes.

Onchain markets need a base asset to price against and settle into. @calilyliu, President of the @solanafndn, on the asset holding that position.

A cross-chain payout means: ↳ sourcing liquidity on the destination chain ↳ picking a route ↳ confirming delivery afterward With Eco, you request a quote and fund an intent, and solvers deliver on the destination chain. Eco reports each intent as filled or settled, and your app reconciles it against the intent ID and transaction hashes. Payouts and policy-based treasury rebalancing run on the same flow.

Stablecoin liquidity sits across exchanges, OTC desks, and pools. How do you price against all of it at once? @strao_, Head of Product at Eco, on how Eco consolidates venue prices at execution time.
