Client for interacting with the Bond Token (ERC20) contract Provides an interface for interacting with ERC20 tokens used for bonding in self-attestations and other platform functions. This client handles token operations like approvals and balance checks, with a test-only minting function.

​
Remarks

Token approvals are required before any operation that needs to transfer tokens (self-attestation, endorsements, etc.)

​
new BondTokenClient()

new BondTokenClient(publicClient, walletClient, contractAddress): BondTokenClient

​
Parameters

publicClient
walletClient
contractAddress
`0x${string}`

​
Returns

BondTokenClient

​
Methods

​
mint()

mint(account, amount): Promise<`0x${string}`>
Mints new bond tokens to a specified account (only for testing)

​
Parameters

account
`0x${string}` Address that will receive the minted tokens
amount
bigint Amount of tokens to mint

​
Returns

Promise<`0x${string}`> Transaction hash

​
Remarks

This function is only available on test networks. In production/mainnet, tokens must be acquired through proper channels (exchanges, transfers, etc).

​
approve()

approve(spender, amount): Promise<`0x${string}`>
Approves an address to spend tokens on behalf of the caller

​
Parameters

spender
`0x${string}` Address that will be approved to spend tokens
amount
bigint Amount of tokens to approve

​
Returns

Promise<`0x${string}`> Transaction hash

​
Example

// Approve tokens for self-attestation
const bondAmount = parseEther('0.0001');
await sdk.bondToken.approve(attestationServiceAddress, bondAmount);

​
balanceOf()

balanceOf(account): Promise<bigint>
Gets the balance of an account

​
Parameters

account
`0x${string}` Address to check balance of

​
Returns

Promise<bigint> Balance of the account

​
Example

// Check account balance
const balance = await sdk.bondToken.balanceOf(userAddress);

​
allowance()

allowance(owner, spender): Promise<bigint>
Gets the allowance of an account to spend another account’s tokens

​
Parameters

owner
`0x${string}` Address of the token owner
spender
`0x${string}` Address of the token spender

​
Returns

Promise<bigint> Amount of tokens the spender is allowed to spend

​
Example

// Check if contract has enough allowance
const currentAllowance = await sdk.bondToken.allowance(userAddress, contractAddress);
if (currentAllowance < requiredAmount) {
  await sdk.bondToken.approve(contractAddress, requiredAmount);
}
