Units

FET is divisible by 10^-18 and the base unit is AFET:

1 fet = 1,000,000,000,000,000,000 afet
1 afet = 0.000000000000000001 fet

ASI balances can be in either integer or string format. However, BitGo recommends using string format to ensure values don't exceed the programmable number limit.

Tokens

The Fetch blockchain doesn't natively support tokens.

Fees

ASI has the following fees:

Minimum fee = 0.0001 FET
Default fee rate = 0.0001 FET

Address Format

Fetch addresses follow the format: fetch1<38-character-bech32-body>. All addresses are exactly 44 characters in length and begin with the fixed prefix fetch1. This format adheres to the following regular expression:

1
/^(fetch)1(['qpzry9x8gf2tvdw0s3jn54khce6mua7l]{38})$/

Memo ID Support

Optionally, a ?memoId=<n> query parameter can be appended to the address for use cases such as identifying transaction metadata. Here, <n> can be any integer.
Using memoId-based addressing eliminates the need to generate multiple deposit addresses per user. A single static address can be reused safely across users and use cases, with the memoId serving as the unique identifier.
Since Fetch uses memoId-based receive addresses, manual consolidation is not required.
