Full Send


Project Links


Description

Full Send operates at the transaction layer between EVM wallets and chains. Users add its RPC endpoint to a compatible wallet while continuing to sign transactions normally; the service does not control private keys. It provides faster inclusion, improved transaction ordering and execution price, revert protection, and protection from frontrunning, sandwich attacks, and other toxic MEV on Ethereum Mainnet and Base Mainnet.

Pylon


Project Links


Description

Pylon is a based appchain platform for deploying customizable appchains without breaking composability with Ethereum. It provides synchronous composability with Ethereum L2s, enabling cross-chain contract calls, asset movement without bridging, and access to L2 liquidity, users, oracles, and tokens. It emphasizes control over governance, upgrades, permissions, branding, and UX while inheriting sequencing and oracle integrations from the underlying chain.

Description

DA Builder is a transaction aggregation service that efficiently groups submitted transactions and posts optimized transactions to Ethereum. It is intended for L2s and rollups, relayers and solvers, and bridges, oracles, and exchanges with frequent transactions, offering fee savings, faster inclusion, nonce management, toxic-MEV protection, and revert protection.

BaiBai

Description

BaiBai is a Prop AMM, a decentralized exchange that updates price curves in real time, dynamically adjusts liquidity depth, and quotes at high frequency to improve execution. It can route trades across multiple liquidity sources, supports natural-language trading commands, and is built on a custom appchain composable with Base and Ethereum; gas fees are not paid by the user.
