Base Writes a Seize Function Into Its Token Standard
ESMA wants to license DeFi front ends, and Abracadabra pays MIM holders four cents.
gm, Defiers!
These are the biggest stories in DeFi and crypto:
- Base shipped Cobalt with condition-bound transactions and a seizeWithMemo function on its B20 token standard
- ESMA proposed licensing the front ends that route EU users into DeFi, plus staking and lending duties
- Abracadabra proposed winding down MIM at about four cents against $21 million of bad debt
- Open USD went live as Stripe's default stablecoin, with Coinbase access due Oct. 1
- Lighter's LIT fell 13% after Robinhood routed its US perps through Bitstamp and its own FCM
Five weeks ago Coinbase put seven US stocks onchain as B20 tokens on Base. On Wednesday Base shipped the function that lets whoever holds the right role take those tokens out of a wallet, move them to an address the issuer has authorized, and attach a note explaining why.
Base activated Cobalt on mainnet, the year's third upgrade, and the release adds seizeWithMemo to the shared B20 surface. The caller needs the SEIZE_ROLE, the source wallet has to be blocked under the token's policy, and the destination has to be approved. Hours earlier ESMA asked the European Commission to license the front ends that route EU users into DeFi.
Coinbase's tokenized equities arrived with transfer restrictions in the contracts in August, and the rest of DeFi wired itself to them anyway. Morpho opened borrowing against them in September, Aave took seven of them as collateral on Base last week, and holder counts passed 4.3 million across chains. Cobalt moves it from each issuer's own contract into the standard every B20 asset shares.
But that’s because issuer control was always the price of admission. The SEC cleared tokenized stocks to trade onchain under an innovation exemption two weeks ago, and an instrument that counts as a security has court orders, sanctions screens and corporate actions attached to it. Those have to execute somewhere.
Tether has been doing this at the issuer level for years, freezing nearly $550 million in Iran-linked USDT last week and drawing a lawsuit over a $42.4 million freeze that preceded the warrant. Base built the same capability once, at the chain layer, for every issuer that wants it.
Who holds the role stays the issuer's decision. That way, a regulator gets a licensed front end to supervise and a named party to serve. The protocols with no role to grant and no company to license are the ones running out of road: Abracadabra is paying MIM holders four cents on $21 million of bad debt, a day after Balancer set its shutdown dates.

Base Ships Cobalt With Conditional Transactions And A Seize Function
Base activated Cobalt on mainnet Sept. 30, its third upgrade of 2026. The release adds seizeWithMemo to the B20 standard, letting an address with the SEIZE_ROLE move a holder's balance to an authorized destination and attach a note. Traders get validity transactions, which sit unsent until a price, balance or block condition holds. Base's docs list the new submission method as running on test networks. Seizure has to be switched on per token.
ESMA Proposes MiCA Rules for DeFi Gateways, Staking and Lending
ESMA asked the European Commission on Sept. 30 to create a gatekeeper category for firms that give clients technical interfaces into DeFi or route their transactions to protocols. Those providers would vet protocols, disclose routing practices and manage conflicts. The regulator also wants crypto service providers barred from every MiCA-licensable service involving noncompliant stablecoins, custody and transfers included. It says the decentralization exemption should be as narrow as possible. The Commission has adopted none of it yet.
Abracadabra Proposes Winding Down MIM at Four Cents on the Dollar
Abracadabra proposed shutting down and paying MIM holders about four cents, in a Snapshot vote that writes SPELL to zero. Collateral backing MIM debt totals about $1.2 million, and roughly $300,000 of that sits in an immutable Arbitrum cauldron the team says would take years to recover. MIM held outside protocol addresses comes to nearly $22 million, leaving about $21 million of bad debt. Deposits peaked above $6.4 billion in January 2022.
Open USD Launches as Stripe's Default Stablecoin
Open Standard launched Open USD on Sept. 30, and Stripe made it the default stablecoin configuration across payments, treasury, payouts and cards. Businesses can still pick another token and keep existing balances. Mastercard's route runs through BVNK, the stablecoin infrastructure firm it bought this year. Visa's platform stays in limited beta with volume and geographic caps, and its API is still coming. Coinbase access begins Oct. 1. All four routes mint and redeem at $1 free.
Lighter Token Drops After Robinhood Perps Plan
Lighter's LIT fell 13% in 24 hours after Robinhood said its US perpetual futures run through Robinhood Derivatives and Bitstamp, a route that skips the decentralized exchange sitting inside Robinhood Wallet. Robinhood is about a quarter of Lighter's perps volume and one of its investors. LIT is down 22% over seven days and about 50% below its record, at a $990 million market value. The Robinhood Chain deployment did $622 million of volume in 24 hours.
