Flow Ft

Flow Ft is an open-source Cadence standard for fungible-token contracts on the Flow blockchain. It defines the FungibleToken interface, a reference ExampleToken implementation, metadata views and a multi-token switchboard. Its resource-oriented design represents owned balances as Vault resources and uses Provider and Receiver capabilities for controlled withdrawals and deposits.

Understand the project

Practical overview

When it fits

Use Flow Ft when a Flow or Cadence project needs a shared fungible-token contract model with resource-based storage, standard transfer behavior and capability-controlled withdrawals.

Who it is for

  • Cadence developers creating fungible-token contracts on Flow.
  • Wallet developers integrating Flow fungible tokens.
  • Teams building Flow dApps or DeFi applications that accept standard-compliant tokens.
  • Developers creating Cadence token-management tooling.

Documented uses

  • Define a Flow fungible-token contract against a common interface.
  • Store token balances as account-owned Vault resources.
  • Transfer tokens through Provider and Receiver capabilities.
  • Build wallet and dApp integrations that interact with conforming tokens.
  • Use generic transaction templates for token interactions.
Before you choose

Requirements & limits

The repository is publicly accessible on GitHub and is published under the Unlicense. The standard contracts are documented as deployed on the Emulator, Testnet, Sandboxnet and Mainnet.

  • Cadence is required for implementing the documented contract interfaces.
  • Token balances use UFix64 with eight decimal places and no negative values.
  • Each token-owning account stores a Vault resource.
  • Provider capabilities can grant persistent or ephemeral withdrawal access, with custom contract logic able to govern withdrawals.
  • The standard contracts are already deployed on the listed Flow networks.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
