Coinbase Launches Coinbase Payments
Coinbase has unveiled Coinbase Payments, an end-to-end checkout solution that lets online merchants accept more than one hundred digital assets directly, convert them to USDC, and settle to bank accounts within twenty-four hours.
Announced on 18 June 2025, the service marries Coinbase Commerce’s on-chain payment flow with a new merchant dashboard, risk-monitoring tools, and plug-ins for Shopify, WooCommerce, and Adobe Commerce.
Transactions are routed through low-cost L2 networks, initially Base, Optimism, and Polygon, so customers pay negligible gas while merchants receive a guaranteed USDC amount insulated from market volatility. For shoppers unwilling to manage self-custody, the checkout also supports direct debits from Coinbase consumer accounts, a feature the company says cuts cart abandonment by removing wallet extensions and seed-phrase friction.
Coinbase’s package includes real-time sanctions screening, address risk scoring, and a smart-contract escrow that releases funds only after order confirmation, addressing fraud and chargeback concerns. Merchants can sweep proceeds to a US bank via ACH, keep balances in USDC for yield strategies, or withdraw to external wallets for DeFi activity.
Looking ahead, Coinbase plans to extend coverage to Europe and Australia in the fourth quarter of 2025 and add support for Solana-based stablecoins plus non-USD payouts next year.
Executives describe Coinbase Payments as a bridge between conventional e-commerce and Web3 infrastructure, arguing that instant, irreversible crypto transactions lower fees relative to card networks and open new cross-border markets without local acquirers.
Particle Network Argues Chain Abstraction Is Now Essential, Not Optional
Particle Network’s latest research essay contends that chain abstraction has moved from buzzword to baseline requirement for Web3 builders in 2025. Authored by COO Ethan “Tabasco” and published on the company’s blog, the piece opens with the blunt claim that fragmented multi-chain workflows are strangling user growth: every manual bridge, gas-token swap and RPC switch drives mainstream users back to centralized exchanges.
The article frames chain abstraction as the logical successor to account abstraction. While ERC-4337 solved wallet UX, it also spawned a sprawl of app-specific smart accounts. By contrast, chain abstraction unifies balances across networks and automates routing, letting users interact with any application from a single asset pool without selecting an origin chain. Particle says this “never bridge again” paradigm is the only way Ethereum can regain UX parity with Solana-style single-chain experiences while preserving the security of a rollup-centric roadmap.
Technical sections highlight universal accounts, smart wallets that expose one canonical address but hold assets on multiple chains via intent-based liquidity fronting. Particle cites its own Universal X trading platform as proof of concept, noting that daily active traders doubled after abstracting bridges and gas.
The essay also praises external work: OneBalance’s resource locks, Rhinestone’s solver market, and EIP-7702’s native batching, arguing that these tools collectively form an ecosystem stack ready for mass adoption this cycle.
Looking ahead, Particle predicts three outcomes: first, leading wallets will embed abstraction layers rather than leaving swaps to dApp front-ends; second, DeFi protocols will compete on execution quality instead of captive liquidity; third, cross-chain MEV will flow to intent solvers, rewarding fast settlement networks and creating new validator revenue streams.
The piece concludes that projects ignoring chain abstraction risk repeating the fate of dial-up ISPs after broadband, a swift decline once seamless alternatives appear.
Stackup Raises $4.2M to Make Crypto Safer
Stackup, a Chicago-based crypto-infrastructure start-up led by former SpaceX flight reliability engineer John Rising, has closed a $4.2 million seed round to bring safety-focused tooling to everyday users. Rising told the outlet that consumer adoption stalls when wallets expose raw contract calls, gas settings and the risk of irreversible loss, shortcomings he likens to “asking airline passengers to service the engines.”
The company, which previously supplied account-abstraction tooling to Coinbase and Trust Wallet, now focuses on giving businesses “centralized control of decentralized assets” through a single dashboard.
The new platform offers role-based permissions, policy-driven transaction approvals and automated treasury flows, abstracting the underlying smart-wallet complexity so finance teams can manage multiple chains without direct contract interaction. Although it still relies on ERC-4337 under the hood, Stackup packages the technology as a compliance-oriented finance stack rather than a developer SDK.
The round was co-led by Archetype and Hypersphere, with participation from Coinbase Ventures, RockawayX, and former GitHub and Plaid executives. Funds will expand engineering headcount, integrate additional chains, and pursue SOC-2 compliance to court fintech partners wary of smart-contract risk.
Rising said early pilots include a consumer-remittance wallet that covers gas with stablecoins and a gaming studio that on-boards players via passkeys while hiding seed phrases entirely.
The company expects to launch a public beta by Q4 2025, targeting builders who want one-click crypto UX without handing keys to custodians.
EIP-7702 Goes Live on Arbitrum, BundleBear Adds Tracking
Arbitrum has activated support for EIP-7702, bringing single-transaction smart-account functionality to the largest roll-up by total value locked. The fork allows any externally owned account to delegate execution to contract code for a single call, enabling batched approvals, gas sponsorship and passkey authentication without migrating to ERC-4337 wallets.
Analytics platform BundleBear confirmed that it has added dedicated dashboards to track adoption. The new pages surface daily counts of type-4 (7702) transactions, average gas savings versus legacy flows, and the proportion of swaps executed with sponsored fees. Early data show a modest but rising curve of smart-wallet transactions since the feature went live earlier this week, mirroring the pattern observed on Ethereum mainnet after Pectra.
Developers can compose 7702 calls with existing ERC-4337 infrastructure — such as paymasters and bundlers — while users retain control of their original private keys.
Eigen Labs Launched EigenCloud for App-Centric Crypto
Eigen Labs has launched EigenCloud, a developer platform designed to abstract away the infrastructure pain points that have slowed mainstream crypto applications. Built on the same restaking research that underpins EigenLayer, the new stack offers serverless smart-contract hosting, intent-based transaction routing, and embedded account-abstraction tooling in a single environment.
At its core, EigenCloud provides “wallet-optional” user flows. Developers can spin up passkey-protected smart accounts that sponsor gas and batch calls behind the scenes, eliminating seed-phrase onboarding. A managed paymaster and bundler service handle fees across multiple EVM chains, while an intent router matches user requests to the cheapest execution path.
Back-end features include verifiable off-chain compute, automatic state snapshots, and real-time analytics. Eigen Labs says the platform is chain-agnostic: contracts can be deployed once and accessed from roll-ups or L1s without custom bridges. Early partners in a closed preview cited sub-second confirmation times and a 40 % reduction in engineering overhead compared with self-hosted stacks.
EigenCloud enters open beta this quarter with a usage-based pricing model; developers can join a waitlist for API keys and documentation. The team frames the release as a bridge to a “crypto app era” in which users interact with branded experiences rather than wallets and block explorers, moving Web3 closer to familiar Web2 paradigms while retaining self-custody under the hood.
