Ethereum and Base abandon shared wallet standard, splitting NFT marketplace account rails

Ethereum and Coinbase-backed Base have abandoned months of talks aimed at a shared next-generation wallet standard, according to a CoinDesk report published September 16, 2026. The split leaves EIP-8141 (Frame Transactions) advancing on Ethereum and EIP-8130 moving on Base, so wallets and marketplace apps that span both networks may need two approval and fee-payment designs instead of one.
For NFT collectors that is marketplace infrastructure news, not a single-drop headline. Modern account-abstraction wallets were supposed to feel like apps: passkeys, flexible recovery, sponsored gas, and batched actions so a mint, listing, or bid could clear without holding ETH solely for fees. CoinDesk said developers tried for months to merge the designs and concluded a forced compromise would cost each chain features it considers core. Derek Chiang of Ethlabs, cited in the report, wrote that Ethereum wanted to be the best version of Ethereum and Base the best version of Base, with interoperability secondary to those goals. Chiang said cooperation broke down the week before the September 16 coverage.
Ethereum’s EIP-8141 Frame Transactions draft emphasizes privacy, censorship resistance, security, and a path away from today’s dominant wallet cryptography if quantum threats arrive. CoinDesk said the Ethereum Foundation this month listed EIP-8141 among execution-layer features it wants for the planned Hegotá upgrade after Glamsterdam later this year. Priority is not a live mainnet guarantee: EIP-8141 remains a draft and is not running on Ethereum today. Base’s EIP-8130 favors flexibility for high-volume applications and compliance needs. The design is already testable on Base’s Vibenet development network and is planned for the Cobalt upgrade, with testnet and mainnet windows listed for September in the same report.
Marketplace Watch cares because OpenSea-style multi-chain desks already ask collectors to hop between Ethereum mainnet, Base, and other L2s for floors, offers, and mints. If native account abstraction diverges, the friction shows up in wallet UX before it shows up in CryptoSlam tables: different transaction construction, different authenticator rules, and different assumptions about who pays gas. Cross-network wallets and marketplace front ends may have to ship dual paths so a Base Cobalt smart account and an Ethereum Hegotá Frame account do not silently fail the same “buy now” click. ERC-4337 remains the shared smart-wallet framework both networks have relied on so far, which softens but does not erase the fragmentation Chiang described as the burden falling on wallets.
The timing overlaps a busy NFT infrastructure week on the same Orange County calendar. 8bitcrypto already covered OpenSea wiring Circle’s Arc stablecoin L1 into NFT trading with USDC fee payment, OpenSea’s Solana OS2 return against Magic Eden rivalry, and Arc USDC settlement predictability for collectors. Those stories expand where trades clear. The Ethereum–Base wallet split decides how accounts will approve and pay for those trades once native account abstraction ships. Collectors should not treat draft EIPs as live marketplace toggles the way Arc’s OpenSea filter is live today. CoinDesk is clear that EIP-8141 is still under development and that Base’s EIP-8130 is in testing ahead of Cobalt’s September schedule.
What the September 16 file proves is narrow and checkable. Talks to unify next-gen wallet rules ended. Ethereum is pushing Frame Transactions toward Hegotá priority lists. Base is advancing EIP-8130 on Vibenet toward Cobalt. Wallets and apps spanning both chains may need two constructions. What it does not prove is an immediate change to OpenSea bid buttons, Base NFT floors, or Ethereum mint gas on Wednesday’s tape. Attribute the product roadmap to the CoinDesk report and primary EIP drafts; do not invent migration dates for marketplace users.
For 8bitcrypto readers on September 16, the clean NFT line is that the two chains collectors use most for EVM marketplace activity walked away from a single native wallet standard. Passkeys, sponsored fees, and batched mint-or-list flows may still arrive—just on diverging rails. Watch Cobalt testnet notes, Hegotá execution-layer shortlists, and whether major marketplace wallets announce dual-standard support before treating either EIP as shipping reality.
