Echo — an on-chain capital formation platform that connects projects and communities through two directions: private rounds led by group leaders and public sales verified via Sonar. In October 2025, Echo was acquired by Coinbase for approximately $375 million, solidifying its role in shaping a new layer of on-chain investing. The platform merges Web3 mechanics, compliance, and tools for safe participation by investors and startups. Echo positions itself as a bridge between traditional venture formats and on-chain transparency. It builds an ecosystem where investors gain direct deal access and projects receive infrastructure for raising funds without intermediaries. After the Coinbase acquisition, Echo effectively became the core of the company’s “on-chain financial stack,” focused on tokenization and new forms of collective investment.

Echo (echo.xyz): positioning and the Coinbase acquisition
Echo emerged as a direct on-chain fundraising tool, allowing projects to conduct rounds among verified investors and public sales via Sonar-ID. The “carry on success only” model aligns all participants’ incentives and differentiates Echo from classic launchpads. In October 2025, Coinbase acquired Echo for $375 million — a deal aimed at building infrastructure for tokenized assets and RWA. The acquisition strengthened integration with the Base ecosystem and increased institutional confidence in on-chain capital formation. Following the purchase, Echo gained resources for scaling: legal support, security audits, and direct access to Coinbase’s user base. This enables it to become part of a future platform for compliant tokens and digital securities. The acquisition signaled that on-chain investing is moving from an experimental phase to an institutional level.
Echo products: Private Groups and Sonar (on-chain ID)
Echo combines two core products:
Private Groups — closed rounds led by investors where commissions are paid only on success;
Sonar — a universal eID enabling one-time KYC/AML verification for participation across multiple project sales.
Key features of Echo and Sonar:
-
Unified eID — reuse your verified identity across all sales;
-
User-controlled access — decide which data to share;
-
Flexible jurisdiction filters — limit participation by country or investor status;
-
Secure data handling — Echo doesn’t process funds, only grants access.
This structure makes Echo a flexible access gateway — projects retain control over their sales while Sonar simply validates participant eligibility.
Additionally, Echo integrates an adaptive API that allows third-party platforms to use Sonar as an external verification module. This creates a network effect: one eID becomes a “pass” to dozens of sales. The platform plans to introduce SBT-based attestations so verification remains on-chain without revealing personal data, gradually turning identity itself into an on-chain asset.
How it works for investors
Investors register, join a Private Group, or participate in a public sale through Sonar-ID. Verification and access take seconds. Echo charges no fixed fees — rewards appear only after capital is returned.
For public sales, Sonar instantly checks eligibility (accreditation, country, limits) and doesn’t interfere with transactions. This preserves confidentiality and clearly divides responsibility between platform and project. The “pay for success” model ensures transparency and motivates leaders to select strong projects.
Investors gain access to detailed dashboards showing sale progress, vesting timelines, and reports. Professional users can follow top leaders’ strategies and use analytics tools. Echo also plans to introduce tokenized participation shares, allowing investors to trade part of their allocation on a secondary market within the ecosystem.
How it works for founders
Founders can choose to run a private round on Echo or a public sale on their own website with Sonar integration. Inside their dashboard, they manage fundraising, compliance tracking, and communication with the Echo team.
Before the table, it’s important to note that Sonar handles KYC and jurisdiction filtering, easing project workload. Successful examples like Plasma and Reppo Labs show that allocations sell out within minutes and sales run smoothly.
Comparison of fundraising paths on Echo
| Parameter | Private Rounds (Echo Private) | Public Sales (via Sonar) |
|---|---|---|
| Where it happens | On Echo, within a group | On the project website, Sonar handles access |
| Managed by | Leader and Echo | Project team |
| Commissions | Carry only upon success | Verification free for users |
| Investor access | Accredited investors | Broad audience |
| Examples | Funds, Reppo Labs | Plasma sale via Sonar |
After the table, it’s worth emphasizing: the approach depends on project goals. Private rounds offer speed and control, while public sales bring wider exposure and community growth. Many teams combine both — starting with Private Groups and later launching a Sonar round to expand their investor base. This staged approach helps reduce risks and build trust between early and retail participants. Echo also provides legal templates and tax support, simplifying the process even for startups new to Web3.
Legal design, risks, and competition
Echo separates layers of responsibility: Sonar doesn’t handle funds, only verifies users. This reduces legal risk and allows projects to comply with local regulations. After the Coinbase acquisition, Echo gained access to regulatory and institutional infrastructure, enabling compliant tokenized securities and RWA products.
Risks remain typical — volatility, deal quality, and jurisdiction restrictions. However, transparency and Coinbase’s backing improve stability and trust in the on-chain fundraising model.
Echo competes with IDO platforms like CoinList and Republic but stands out by rejecting lottery-style allocations. Its model prioritizes deal quality over hype. In the future, Echo could become part of a registered marketplace for tokenized equities and bonds if Coinbase executes its compliant-RWA strategy — reinforcing Echo’s role as the on-chain compliance standard.
Conclusions and prospects for Echo
Echo transforms on-chain investing into a scalable, compliant, and transparent process. Private Groups and Sonar form a universal access layer available to both retail and institutional participants. After integration with Coinbase, the project expands beyond Web3 startups into real-world assets and regulated capital markets.
Echo has already helped raise hundreds of millions of dollars, proving that on-chain fundraising can be safe, simple, and efficient. It builds a new trust architecture between projects, investors, and infrastructure — bringing capital closer to users. In the coming years, Echo is set to become a vital part of the Base ecosystem, offering not only a fundraising platform but also tools for secondary trading of tokenized assets. This evolution could set the standard for the entire on-chain capital formation industry.
