Mapping

Tokens are mapped using chain code and token code. This allows the FIO Handle to be mapped to different public address, even for tokens on the same chain.

Standards

FIO Foundation publishes a coding standard to ensure all clients use the same codes. Over 6,000 tokens have been standardize, but anyone can add new codes as they are launched.

Chain Level

FIO Handle can also be mapped at the chain level, ensuring every current and future token code is mapped to a single FIO Handle.

URI Parameters

Mappings support uri parameters in the public address, which enables the transaction to include additional parameters, such as memo or destination tag.

FIO Domains

The FIO Domain is part of the FIO Handle and can be used to brand or customize the handle itself.

Most users will register a FIO Handle on one of the many public domains maintained by the community, e.g. @hodl, @wallet.

Many integrators choose to offer FIO Handles on branded domains, e.g. @opera, @edge.

FIO Domain owner can choose to make the domain public, which allows anyone to register FIO Handles on it, or keep it private, which make them the only registrar.

Just like FIO Handle, FIO Domains are NFTs owned and controlled by a private key on the FIO Chain.

FIO Domain ownership can be transferred to any public key.

FIO Domains can also be wrapped (transferred over) to Polygon blockchain, so that they can be listed on public marketplaces, such as Opensea.

Additional Domain Information

Renewals

• To reduce squatting, FIO Domains are valid for a period of 1 year from the time of their registration.

• If not renewed, the domain:

• Disallows any new FIO Handle registrations (0-30 days after expiration)
• Stops FIO Handles on that domain from functioning (31-90 days after expiration)
• Domain and all FIO Handles on that domain are burned (90+ days after expiration)

• Anyone can renew any domain, even if they do not own it, as long as they pay the renewal fee

Wrapped FIO Domains on Polygon

• FIO Domains NFT can be wrapped (moved) to the Polygon chain to enable trading on common NFT Marketplaces.

• Wrapping and unwrapping (moving back to FIO Chain) is accomplished using a decentralized FIO Bridge operated by a subset of Block Producers.
