If you're looking for a service that offers a centralized record of your crypto activity across exchanges, FindMyTokens is a good choice. The service helps people recover lost tokens by matching wallet transactions with exchange deposit addresses. It offers a detailed report of interactions with centralized exchanges, including timestamps for each interaction and blockchain and wallet addresses involved. The system supports major EVM Chains like Ethereum, Binance Smart Chain and Arbitrum. FindMyTokens offers tiered pricing, including a $14.99 Starter plan for a single wallet report and an Institutional plan for more advanced analysis.
Another option is DataTrails. Although it's geared more toward transparency and audit trails for digital content and data, the service offers immutable and verifiable records that could be used as a centralized record of your crypto activity. Its transparency technology guarantees the integrity and provenance of the data, which could be important for investors trying to keep track of their cryptocurrency activity. DataTrails offers a 30-day free trial and several subscription tiers to accommodate different needs.
