Listing an NFT for sale means signing a marketplace order that authorizes a buyer to purchase your token. Here's how the approval and order mechanism works, where the fees sit, and what to watch for.

Minting an NFT means executing a transaction that creates a token on-chain and assigns it to your wallet. Here's what actually happens, what you need, and where the risks sit.

NFT metadata is the JSON file that defines what an NFT represents — its name, image URL, and traits. The token on-chain is just an ID; the metadata is everything else. Here's how to read it directly from the contract and what to look for.

The contract address is the only identifier that matters for NFT authenticity — not the image, name, or listing. This post explains the five-step verification process and where it gets complicated.

Exporting wallet transaction history depends on whether you're on a centralised exchange or a self-custody wallet. The methods differ, the data is incomplete by default, and combining sources is almost always necessary.

Crypto losses don't become deductions automatically — you have to realize them, document four specific data points, and apply them correctly. Here's how the loss rules work, including carryforward limits, the missing wash sale rule, and what records you actually need.

Airdrop tokens are taxable income under IRS rules — calculated at fair market value on the date of receipt, even if you never sell. Here's how the mechanism works, when the taxable event occurs, and what records you need.

Crypto tax tools automate transaction import and cost basis calculation — but they have real failure modes. Here's how the workflow actually works and what to verify before you file.

Cost basis is the starting number behind every crypto tax calculation. This post covers the accounting methods the IRS permits, why cross-wallet transfers break automatic tracking, how DeFi complicates basis further, and what 1099-DA changes — and doesn't.
