Celer Network (celer)

Multi-chain bridging protocol using SGN (State Guardian Network) for cross-chain message validation and token transfers.

Fact	Value
Category	Bridges
Family	none
Namespace	`Celer` on ethereum, optimism, bsc, polygon, arbitrum, avalanche
Chains	ethereum, optimism, bsc, polygon, arbitrum, avalanche

Notes

send for ERC-20 tokens, sendNative for native tokens (ETH, BNB, AVAX, etc.)
nonce is used for unique transfer identification — can set to 0 or use block.timestamp
maxSlippage is in basis points (1 = 0.01%, 100 = 1%, 5000 = 50%)
Uses SGN validators to verify cross-chain messages
Finality: typically 5-20 minutes depending on chain confirmation requirements
Requires ERC-20 approval to the Bridge address

On Ethereum, Celer is a namespace: its contracts need no import.

function main() {
  // Ethereum's bridge, `0x5427FEFA711Eff984124bFBB1AB6fbf5E3DA1820`.
  require(Celer.Bridge != 0);
}
