Celo support
cNGN is now deployed on Celo. The Contract Addresses page lists both the mainnet contract (0xF6829D7393dAe24509eb1E52eE8e572e2E271a4f) and the
testnet contract (0xa188439ccCEe9A6aa0E842f9c17C1b00C7B4dd4D).Celo is an EVM chain, so withdrawals, bridging, and address whitelisting work exactly as
they do on the other EVM networks. Resolve its networkId per environment from
Get Networks; see the Networks guide.Webhooks
Full webhook event coverage
Every documented webhook event is now delivered:- On-chain deposits now fire
deposit.completedwithtrx_type: crypto_deposit, carrying both the source-network hash (extl_trx_hash) and the mint hash (base_trx_hash). There is no precedingdeposit.receivedfor on-chain deposits. - Redemptions now fire
redemption.completedwhen the bank payout settles, andtransaction.failed(withreason: "Provider failed to process payout") when it does not. Redeemed cNGN is automatically reverted to your balance on payout failure. - The Webhooks guide now documents exact
sample payloads for all five events, including the three
transaction.failedvariants, plus a field-presence matrix.
