  --data '{ "address": "example", "label": "example" }'

Link an on-chain wallet address to your account.

The address is normalized per chain before storage: EVM/bech32 are lowercased, base58 (Solana, Bitcoin legacy) keeps its casing because those encodings are case-SENSITIVE. Duplicate linking returns 409.
