Smart accounts
Safe 1.4.1 smart accounts at the canonical addresses, with passkey login, so new users do not need a seed phrase to get started.

Built in from day one
A chain that ships with the app layer
Most chains hand you a blank network. Gully Chain launches with the accounts, gas, names, payments and safety tools that users and builders would otherwise have to bolt on themselves.
Gas, handled
Gas can be sponsored or paid in USDC or glUSD through an ERC-4337 paymaster. No native gas token needed to make a first transaction.
.gully names
Readable names like alice.gully instead of long hex addresses, available across the chain.
DeepCore launchpad
The DeepCore launchpad is built in, and the DeepCore team deploys on testnet.
Payments native
Gully Pay x402 pay-per-call payments and glUSD, so apps and APIs can charge per request on-chain.
Safer by default
Every token is mapped by HolderMaps and scanned by Gully Security. A first-come-first-served sequencer means no classic sandwich attacks.
The stack
How Gully Chain fits together
Gully Chain is an Arbitrum Orbit chain. It runs as a layer 3 and settles to Arbitrum, which in turn settles to Ethereum.
- 01Your appUsers sign in with passkeys, pay gas in stablecoins or not at all, and send to .gully names.
- 02Gully Chain L3Arbitrum Orbit with a first-come-first-served sequencer, Stylus for Rust contracts and Uniswap v3 liquidity.
- 03ArbitrumTestnet settles to Arbitrum Sepolia. Mainnet will settle to Arbitrum One.
- 04EthereumArbitrum One settles to Ethereum, so the chain inherits that security path.
