Agora Sandbox API

Testnet Tokens

The chains, tokens, and faucets the sandbox uses.
← Switch to the Production API

This is the sandbox. It runs on testnets only. Never send real money or real tokens to an address or bank account the sandbox returns.

The sandbox is subject to the Beta Features section of our Terms of Use.

The sandbox runs on two EVM testnets, avalanche-fuji and ethereum-sepolia. Its tokens are testnet tokens with no value.

Tokens

Both tokens have the same address on Fuji and Sepolia.

Use CTK wherever your production integration would use USDC. See On-Chain Deposits for how amounts convert.

Get tokens

Gas

Any wallet that sends a transaction, such as a deposit or an AUSD faucet request, needs a little testnet gas. The sandbox doesn’t provide it, so you will need to get it from a public faucet:

avalanche-fujiFuji AVAXAvalanche Builder Console
ethereum-sepoliaSepolia ETHGoogle Cloud Web3 Faucet

These faucets are run by third parties. They may ask you to sign in, and they limit how often you can claim.

CTK

Call POST /v0/sandbox/faucet with an address and a network. It sends 1,000 CTK, usually within a minute.

curl -s -X POST https://api.sandbox.agora.finance/v0/sandbox/faucet \
  -H "Authorization: Bearer $JWT" -H "Content-Type: application/json" \
  -d '{"address":"0xYourWallet","network":"avalanche-fuji"}'

Send it to a wallet you control, then deposit from that wallet. CTK sent by the faucet straight to a deposit address is not paid out. The faucet send doesn’t appear in your transactions, so check the wallet’s balance.

AUSD

Call requestFunds(address) on the AUSD faucet contract, 0xd236c18D274E54FAccC3dd9DDA4b27965a73ee6C. It has the same address on Fuji and Sepolia and mints 10,000 AUSD per request. Your wallet needs a little gas to send the transaction. For a viem example, see Getting Testnet Tokens.

You can also mint AUSD from CTK with a ctk → ausd route. See On-Chain Deposits.

Explorers

The API returns a transactionHash for each on-chain leg. Look it up on Snowtrace (Fuji) or Etherscan (Sepolia).
