Eco has introduced Flash Intents, a routing mode that lets solvers execute large same-chain stablecoin orders using a user’s own capital.
Eco, a protocol for real-time stablecoin movement, has launched Flash Intents, a new routing mode within its Eco Routes infrastructure.
The feature is designed for same-chain stablecoin swaps, particularly larger orders where solver-managed liquidity may be insufficient.
Eco operates as an intents-based protocol, where third-party solvers monitor order requests and compete to fulfil them on optimal terms. Its standard intent configuration has historically relied on solvers using their own liquidity to complete transactions. While this can be the fastest option for smaller orders, it may limit capacity for larger on-chain transactions.
Flash Intents addresses this constraint by allowing solvers to fulfil orders atomically using the user’s own capital. In this mode, the solver routes the user’s funds through the most efficient, lowest-cost swap pathway. The feature is intended for scenarios where no direct liquidity match exists or where complex, multi-step routing is more efficient for high-volume orders.
A key technical feature of Flash Intents is atomic execution. This ensures that the swap either completes in full or does not occur, removing the risk of partial fills. The protocol does not require users to trust the solver beyond the constraints encoded in the intent.
For developers, Flash Intents is designed to integrate seamlessly. The feature functions as a new “prover type” within the existing Eco Routes API. Applications already using Eco Routes will inherit the capability automatically, without contract upgrades or API migrations.
The protocol is designed to select the optimal routing mode — either Standard or Flash — based on available pathways and competition between solvers.
