Every Sonar token sale,
read from the sale contracts
Sonar publishes no directory of its sales, so this one is built from the chain: every sale contract Echo has deployed, from Plasma's vault in July 2025 to the current factory-made SettlementSales, with totals read straight from the contracts and Echo's public record supplying names, schedules and pricing. Click a sale for its demand curve, timeline and bid book statistics.

Accepted vs. demand
Green is what the project took; faded is total demand (log scale, since MegaETH's $1.39B of bids would otherwise flatten everything else). Gold marks a price set by auction.

How this is built
- Three generations of contracts. The first five sales (Plasma, MegaETH, Gensyn, Infinex; Jul 2025 – Jan 2026) ran on bespoke contracts deployed one at a time by Echo's operations wallet
0x17156a9d8388A3b158d57B29912380336324947C; enumerating that wallet's contract creations on Ethereum and Base finds them, along with rehearsal deployments that never opened (listed below). From January 2026 Echo deploys through a SettlementSaleFactory that emits a sale-created event with the sale UUID and contract address: a first generation on Ethereum, Base and MegaETH, then a second from March 2026 (Base, Ethereum) and June 2026 (Monad). The factory logs are the complete list of everything since.
- What "accepted" means. The contract's accepted total after settlement: money the project kept. Demand is everything committed, including bids refunded because the sale was oversubscribed, the bid was below the clearing price, or a tier was capped. For Plasma the demand figure is the vault deposits reported by press, because the on-chain contract only ever held the $50M that cleared.
- Fill is demand ÷ what the sale could take: offered supply × price, or the hard cap revealed at settlement when accepted is below demand.
- Price. Fixed-price sales show Echo's price. English auctions show the uniform clearing price computed from the on-chain bid book: the highest price at which cumulative demand buys the whole offer (undersubscribed auctions clear at the floor). After settlement it is reconciled to accepted ÷ supply when the two agree; when they don't, fewer tokens were allocated than offered and the book price stands, with the token count derived from accepted ÷ price.
- FDV and % of supply need the token's total supply, which neither the chain nor Echo provides; they appear only where a supply figure is on record (source on each sale's page).
- Excluded. Test-tenancy deployments, rehearsals that never opened, and duplicate deployments of the same sale UUID (the contract that took the commitments is shown).
- Payment tokens so far are USDC, USDT, USDT0, DAI and EURC, all 6- or 18-decimal stablecoins summed at par.
- This is a neutral directory, not investment advice or an offer. Token prices after the sale are deliberately not shown.
