System Contracts

System and bridge contract addresses on Gravity Mainnet (L1).

The addresses on this page are for Gravity Mainnet (L1, chain ID 127001). For the legacy Gravity Alpha Mainnet (L2, Arbitrum Nitro, chain ID 1625) rollup contracts (rollup, inbox, outbox, sequencer, gateways), see Gravity Alpha Mainnet (L2) Contracts.

Gravity L1 system runtime contracts live at fixed, well-known addresses in the 0x1625F0000–0x1625F5xxx range. They cannot be re-deployed; adding a new system contract requires a hardfork.

System runtime contracts

Consensus engine (0x1625F0xxx)

Address	Contract	Purpose

Oracle (0x1625F4xxx)

Address	Contract	Purpose
0x1625F4000	NativeOracle	Verified external data (blockchains, JWK providers, DNS)
0x1625F4001	JWKManager	JWKs for keyless account authentication
0x1625F4002	OracleRequestQueue	User-initiated on-demand oracle requests — address reserved, not yet deployed (eth_getCode returns 0x); do not integrate against it yet

Precompiles (0x1625F5xxx)

Address	Contract	Purpose
0x1625F5000	NativeMintPrecompile	Authorized native G mint
0x1625F5001	BlsPopVerifyPrecompile	BLS12-381 proof-of-possession verification

Cross-chain bridge

The canonical bridge consists of two contracts on Ethereum mainnet, paired with the GBridgeReceiver contract on Gravity L1 (deployed at genesis) that mints native G via the native-mint precompile once the consensus engine relays a verified message through the native oracle:

Contract	Address	Purpose
GravityPortal	0x76cf8526Fa9461e50B2c6702a7246ce6915f6E53	Charges ETH fees, emits MessageSent events for consensus
GBridgeSender	0xE82c61Ac9Ec2041b493118051afa4F18a55dC876	Locks G ERC-20 from the user, forwards the bridge message to the Portal
Owner (multisig)	0xbD6e434dB90FD8AD4E28d85C133AD34cA6fbfB6D	Gnosis Safe 3-of-6, owner of both Portal and Sender

Both Ethereum contracts are owned by a 3-of-6 Gnosis Safe multisig. For the end-user bridging flow, see How to Get G.

Token contracts

For the canonical ERC-20 token list on Gravity L1 (native G, wG, and bridged assets as their bridge routes go live), see Token Contracts on Gravity.
