Minting Testnet Tokens


The Bitfinity Testnet supports minting testnet tokens which users can pay for gas fees when deploying their dapps.

We support minting testnet tokens in a number of ways.

Minting on Discord

We have two endpoints for minting tokens. We support both IC and Ethereum users. For the JSON-RPC endpoint, we use the ic_mint_native_token method, while for the IC endpoint, we use the mint_native_tokens method.

Minting through the Web Faucet

Navigate to the faucet interface, then click on the mint tokens button. Thsi will conenct to your metamask, and after waiting a few seconds you will receive testnet tokens.

Mint Tokens

Minting through the EVM JSON RPC API

For the JSON-RPC endpoint, we use the ic_mint_native_token endpoint. As an example, see the code samples below:

  • Minting native testnet tokens for the Ethereum address 0xfB0D14c07DA958bBB257346F49b2E9C9382c4888:

An example curl command to mint tokens.

-X POST -H 'content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":"67","method":"ic_mintNativeToken","params":["0xfB0D14c07DA958bBB257346F49b2E9C9382c4888", "0xde0b6b3a76400000000000000"]}'

For better readability, please see the JSON blob for the parameters.

"jsonrpc": "2.0",
"id": 1,
"method": "ic_mintNativeToken",
"params": {
"address": "0xfB0D14c07DA958bBB257346F49b2E9C9382c4888",
"amount": "0x3e8"

After minting tokens, if the request was successful, you can check your balance using the eth_getBalance method, or you can check the balance from your wallet. For example, see how to do this with curl:

-X POST -H 'content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":"67","method":"eth_getBalance","params":["0xfB0D14c07DA958bBB257346F49b2E9C9382c4888", "latest"]}'

Minting through the IC

  • It is also possible to directly mint testnet native token using the Internet Computer. Here is an example with DFX, minting tokens for the address. 0xfB0D14c07DA958bBB257346F49b2E9C9382c4888

Note that the endpoint name is mint_native_tokens

dfx canister call --network=ic BITFINITY_CANISTER_URL mint_native_tokens '(opt \"0x1234567890123456789012345678901234567890\", 10000000000000000000)'
