Token Types

XRPL supports multiple token standards. Ledger existence proves on-chain objects and related transactions — not issuer reputation, legal rights, or off-ledger backing.

Multi-Purpose Tokens (MPTs)

A newer XRPL fungible-token standard designed for more flexible tokenization use cases.

MPTs support tokenization features beyond the original Trust Line Token model. The presence of an MPT on XRPL proves the ledger object and related transactions exist; it does not independently verify the issuer, backing, legal rights, or economic claims.

What you'll see

  • New MPT issuances
  • Tokenization activity using the MPT standard

How it's validated

Confirmed from successful transactions in validated ledgers and the resulting MPTokenIssuance ledger entries.

Non-Fungible Tokens (NFTs)

Unique XRPL tokens that can represent digital items, collectibles, or claims associated with real-world assets.

XRPL NFTs can represent collectible or application-specific items. An NFT’s existence and ownership can be verified on the ledger, but the ledger record alone does not prove off-ledger legal rights, asset backing, authenticity, or financial value.

What you'll see

  • Notable mints and transfers
  • Your own SurferX Syndicate NFT status

How it's validated

Ownership is confirmed through account_nfts against a validated ledger—the same ledger check used for Syndicate NFT verification.

Trust Line Tokens

The original XRPL fungible asset type—used for stablecoins, community credits, and custom currencies.

Trust Line Tokens are held through XRPL trust lines. A holder generally establishes a trust line before receiving the asset, while actions that explicitly acquire a token, such as some decentralized exchange transactions, can create the required trust line automatically. Trust lines help prevent accounts from being forced to hold unwanted tokens.

What you'll see

  • Stablecoin issuance and redemption activity
  • Custom currency trust line creation

How it's validated

Confirmed from validated XRPL transactions and RippleState trust line ledger entries.
