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.

Transaction history in crypto lives in multiple places — exchange accounts, block explorers, and separate records per chain. Here's where to look and how to compile a complete picture.

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.

DeFi creates more taxable events than almost any other financial activity — and most generate no automatic reporting. Here's how the mechanics work: swaps, liquidity provision, yield, and airdrops.

NFT taxes involve more taxable events than standard crypto — disposals, NFT-for-NFT trades, protocol airdrops, and creator income each have different mechanics. This explains the calculation, the open collectibles question, and where valuation gets hard.

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.

Crypto is treated as property under US tax law — every sale, trade, and disposal is a reportable event. Here's how Form 8949, Schedule D, and the new 1099-DA fit together.

Choosing a validator is a risk evaluation exercise, not just a commission comparison. Here's what uptime, self-stake, slashing history, and protocol-specific mechanics actually mean for your decision.

How staking rewards are claimed differs by protocol. Solo ETH validators, liquid staking (Lido, Rocket Pool), Cosmos chains, and Solana each handle reward accrual and claiming differently — some automatic, some requiring manual transactions.
