Types: Token

Token is a class which can represent any ERC20-compatible token on any given network, and is a data class.

The Synapse Protocol SDK provides pre-defined Token instances for all tokens supported by the Synapse Protocol on all supported networks in the Tokens namespace, which is easily imported like so:

import {Tokens, ChainId} from "@synapseprotocol/sdk";

console.log(Tokens.USDC.address(ChainId.BSC));

You should not expect to ever have to instantiate a Token manually, and using a manually instantiated Token with various functions in the SDK will likely cause undefined behavior.

Instance variables

Unless otherwise specified, all instance variables are read only and set by the constructor.

• name (string) - The "official" name of the token. Example: "USD Circle" (for USDC)
• symbol (string) - Symbol the token is known by both on and off-chain. Examples: "USDT" (Tether's USD stablecoin), "DOGE" (for Dogecoin)
• addresses ({ [chainId: number] => string }) - This field is similarly shaped to decimals, in that it is a mapping with shape chain id => address for chain (string), containing the on-chain addresses of this token for respective Chain ID values.

Functions

• address
  • Returns the on-chain address of this token respective to the passed Chain ID.
  • Params:
    • chainId: number - Chain ID of the chain for which you want this token's on-chain address.
  • Returns:
    • string
    • The on-chain address of this token respective to network, or null if the token is not supported by the Synapse Protocol on the given network.
• decimals
  • Returns the on-chain decimals value of this token respective to the passed ChainID.
  • Params:
    • chainId: number - Chain ID of the chain for which you want this token's on-chain decimals.
  • Returns:
    • number
    • The on-chain decimals value of this token respective to network, or null if the token is not supported by the Synapse Protocol on the given network.
