Token Balances

Read ERC-20 token balances directly from the blockchain. Equivalent to the SDK’s internal getErc20Balance().

Contract Methods

`balanceOf(account)`

Returns the token balance for an address.

Parameter	Type	Description
`account`	`address`	Wallet address to query

Returns: uint256 — token balance in the token’s smallest unit

`decimals()`

Returns the number of decimals the token uses. Returns: uint8 — decimal places (e.g., 6 for USDC, 18 for account shares)

Usage

Call these on any ERC-20 token contract, including:

What to check	Contract to call	Address source from Account Discovery
Account share balance	BoringVault	`vault.boringVaultAddress`
Deposit token balance	ERC-20 token	`vault.supportedAssets[].address`

To convert a raw balance to a human-readable amount, divide by 10 ^ decimals. For example, a USDC balanceOf of 1000000000 with decimals of 6 = 1,000 USDC.
