Polymesh is a permissioned blockchain designed for regulated assets. This guide covers Polymesh-specific features when using DFNS wallets.

​
Identity requirements

Polymesh requires identity verification before you can send assets. While any address can receive funds, sending requires a Decentralized Identifier (DID).

​
Getting a DID

  1. Create a DFNS wallet for Polymesh
  2. Register your wallet address on the Polymesh Portal
  3. Complete identity verification to receive a DID
  4. Once registered, DFNS stores the DID and you can send transactions
Without a DID, your wallet can only receive assets. You must complete identity registration before sending any transactions.

​
Asset-specific DIDs

For regulated assets (RWAs), you may need separate identity verification for each asset class. DFNS does not support portfolio management - each wallet has a single identity.

​
Transfers

Use the Transfer Asset endpoint for Polymesh transfers:
  • Native POLYX: Use kind: Native

​
RWA transactions

For Real World Asset (RWA) transactions, you can use:

​
Transaction expiration

DFNS builds Polymesh transactions with a 6-hour expiration: the transaction must be broadcast within 6 hours of being built, otherwise it expires and must be rebuilt and re-signed. This applies to all transactions, including transfers, and gives this much time to sign and broadcast even if the signing infrastructure is temporarily unavailable (for example an unreachable on-prem signer).
