SkyBridge V2
SkyBridge V2 is deployed across 11 chains at a uniform Diamond address: Ethereum, Polygon, Base, Arbitrum One, Optimism, Avalanche C-Chain, BNB Chain, Unichain, Soneium, Ink, and MegaETH. Robinhood Chain (chainId 4663) is also live - two lanes only (⇄ Ethereum, ⇄ Base) - but at its own, divergent address; see below.
Diamond (11-chain fleet)
The Diamond proxy address is identical on these 11 chains (CREATE2-deployed):
| Contract | Address | Explorer |
|---|---|---|
SkyBridge Diamond (EIP-2535 proxy) | 0x14fbb1eD5BC098B4Ea236dcE0941EDB02e967b44 | Etherscan |
Diamond & EntryPoint (Robinhood Chain)
Robinhood's Diamond deploys at its own address rather than the fleet's uniform one, because its genesis facets were compiled from a later source snapshot than the fleet's - the logic is identical, but a few bytes of compiler metadata differ, which is enough to change the CREATE2 output address. This is not a misdeploy; see Diamond & Facets for the mechanism. It cascades to any token CREATE3-deployed from this Diamond - see the sAFX row below.
| Contract | Address | Explorer |
|---|---|---|
SkyBridge Diamond (EIP-2535 proxy) | 0xEF69D1115EC4742F7CECa7cAAD8DdcB5E4695456 | Blockscout |
SkyBridgeEntryPoint (ERC-1967 / UUPS proxy) | 0x63743c4c3E2bf2ae7958c7e79D265372Ef40E315 | Blockscout |
EntryPoint (per chain)
Each chain has its own SkyBridgeEntryPoint (ERC-1967 / UUPS proxy). The proxy address is what users interact with.
Note: Six chains (Polygon, Arbitrum One, Optimism, Avalanche C-Chain, BNB Chain, and Soneium) share the EntryPoint proxy address
0x126C7cce26214f04FDa627AA901696f3835d9FfC. This is not a collision - these chains had an identical deployer nonce at the time of deployment, so CREATE produces the same address deterministically on each.

Arbitrum Canonical Inboxes (Rail 5)
Rail 5 (Arb Canonical ETH) deposits native ETH into Arbitrum-stack chains via each chain's canonical Delayed Inbox, registered in the L1 EntryPoint's arbitrumInboxes mapping. These Inbox contracts are Offchain Labs / Robinhood infrastructure, not SkyBridge contracts - listed here for reference since the EntryPoint calls them directly.

Bridged AFX (sAFX) Addresses
SkyBridge AFX (sAFX) is AFX's canonical bridged representation on every non-Ethereum chain (Ethereum remains AFX's canonical home, listed above). It is deployed via CREATE3 with a salt derived from the canonical AFX address, so it lands at a single deterministic address that is identical across the 11-chain fleet: 0x7F340bb1Bd152E70761C70665E9D7c0aA3c4d3F5. Robinhood is the exception: its Diamond deploys at its own address (see above), and CREATE3's salt derivation is scoped to the deploying Diamond, so Robinhood's sAFX rep lands at a different, chain-specific address instead. See Token Model for the mechanism.
