The December 15 STG-to-ZRO Migration Deadline Nears as Coinbase Suspends Trading
Key Facts
Coinbase has set December 15, 2026, as the deadline for STG token holders to migrate to ZRO through a self-custody wallet and migration portal, according to the platform’s help page. This means holders covered by the deadline must transfer their holdings before the date set by the asset issuer. Coinbase said the migration requires a self-custody wallet and referred users to a dedicated portal to complete it. LayerZero also confirmed that transfers will not be supported after December 15. The deadline puts the STG-to-ZRO migration at the forefront of the practical impact on holders, alongside Coinbase’s notice regarding trading in STG and PYR.
Coinbase’s page lists December 15, 2026, as the deadline for migrating STG to ZRO and describes a process that uses a self-custody wallet and an STG migration portal. The platform says the deadline is tied to a date set by the asset issuer, making it necessary for affected customers to move their holdings to a self-custody wallet before it expires. LayerZero’s update gave the same date, saying transfers would not be available after December 15. The platform’s guidance is therefore consistent with the statement from the party associated with the transition about when transfer support will end. The available information provides no further details about technical requirements or migration fees.
In its notice on STG and PYR, Coinbase said it had moved the tokens’ order books to “limit-only” mode, meaning users can place and cancel limit orders, although matches may execute. Under the restrictions set by the platform, this mode allows users to continue handling existing or new orders, according to the notice. Coinbase also said STG and PYR balances would remain available to customers and withdrawals would continue to be possible. This distinguishes the suspension of trading from continued access to and withdrawal of balances, according to the notice. The available notice did not state the current trading suspension date cited in the draft.
Coinbase said it regularly reviews listed assets to ensure they continue to meet its listing standards, and that the decision to suspend trading followed recent reviews. The available notice did not give a specific reason for either STG or PYR, linking the decision only to the reviews and the platform’s standards. Coinbase said the trading suspension covers Coinbase.com, including simple and advanced trading, as well as Coinbase Exchange and Coinbase Prime. The scope of the notice shows that the action applies to more than one of the platform’s trading interfaces. Coinbase’s wording ties the decision to its periodic review of listed assets.
In an update dated September 15, 2026, LayerZero said it would work with exchanges, market makers, custodians and ecosystem partners to support the transition from STG to ZRO before the deadline. The plan involves multiple parties in supporting the transition, while the step for token holders requires a self-custody wallet and migration portal. LayerZero said transfers would remain available until December 15 and would not be supported after that date. The deadline gives STG holders a clear timeframe to complete the transfer, while balances remain withdrawable under Coinbase’s notice. The migration deadline is the future date specified in Coinbase’s and LayerZero’s guidance.
