Echo group-led deals on Base, decoded
Echo is the on-chain investment platform where members follow a group lead into individual deals, with everyone's USDC commitment pooled into a single on-chain entity that invests in the target project. rotki decodes the on-chain side of that flow on Base: your commitment into a deal pool, Echo's platform fee, and full refunds if you're deregistered before the pool closes.
Supported features
- Deal commitment: the USDC (or other deal-currency token) you send to follow a group lead into a deal is tagged as a deposit-to-protocol event against the Echo counterparty, with the deal pool address recorded in the notes.
- Platform fee: the on-chain fee Echo charges on top of your commitment is broken out as a fee-subtype event, so your committed capital and the fee are accounted for separately rather than as one inflated spend.
- Pool refund: if you're deregistered from a deal pool (full refund), the USDC you get back is tagged as a withdraw-from-protocol event against Echo and linked to the deal pool address.
Limitations
- Echo decoding currently ships on Base only.
- Only full refunds (a member being deregistered from a pool) are decoded. Partial refunds don't emit the deregistration event, so they appear as ordinary token receives; reconcile them manually if you have one.
- Token or equity distributions that arrive after a deal closes (project tokens, vested receivables, group-lead carry) appear as ordinary receives, not as Echo-counterparty events.
Setup
- 1In rotki, add the Base address you used to commit to Echo deals.
- 2In rotki, open History and let the initial sync run. Deal commitments, Echo platform fees, and full pool refunds are decoded automatically.
Frequently asked questions
Are Echo platform fees separated from my commitment?
Yes. The platform fee is split out as a fee-subtype event against the Echo counterparty, so the amount you actually committed to the deal pool stays clean for cost-basis purposes.
Does rotki read Echo activity from its own servers?
No. rotki is a local application that talks directly to the Base RPC endpoint you configure - the public default, a third-party provider, or your own node. The query goes from your computer to that endpoint without passing through any rotki-operated server.
