Examples

LINK|0|BTC|1234|BTC|4321|Linking FILE upload to TICK
This example links a BTC `FILE` upload with `ACTION_INDEX` 1234 with a BTC `ISSUE` transaction on a `TICK` associated with `ACTION_INDEX` 4321

LINK|0|BTC|1234|DOGE|6666|Linking TICK with FILE upload on DOGE
This example links a BTC `FILE` upload with `ACTION_INDEX` 1234 with a DOGE `ISSUE` transaction on a `TICK` associated with `ACTION_INDEX` 6666

Rules

COIN1 and COIN2 values must be a valid coin network (BTC, LTC, DOGE, etc)
COIN1_ACTION_INDEX must point to a valid ACTION_INDEX on the COIN1 network
COIN2_ACTION_INDEX must point to a valid ACTION_INDEX on the COIN2 network
When COIN2_ACTION_INDEX resolves to a local ISSUE (i.e. linking against a TICK):
- SOURCE must be the current owner of that TICK
- The TICK’s ownership must not be currently escrowed (ORDER / SWAP / DISPENSER with GIVE_OWNERSHIP=1 is open against this TICK) — see Token Ownership Sales
- Cross-chain ISSUE targets cannot be validated locally; the owner / escrow checks are skipped when COIN2 is not the local network

Notes

LINK’s primary use case is attaching a FILE to a TICK (logo, terms, documentation), but it is a generic action-to-action pointer and supports other pairings (cross-chain attestation, etc.)
The owner-validation rule above makes LINK the official content-association mechanism for NFTs — only a token’s owner can attach files to it. The protocol attaches no display semantics to linked files; what renders is decided by the token’s Token Information Standard metadata. See the NFT Standard.
The same rule makes LINK the attestation mechanism for project registries — a TICK-type LIST linked to a token’s ISSUE by its owner is that project’s official-token roster. See the Project Registry Standard.
