JPMorgan takes JPM Coin from Base to Ethereum mainnet

JPMorgan has made its dollar deposit token JPM Coin available to institutional clients on Ethereum’s mainnet, adding a public network to its earlier Base deployment and widening where the bank’s clients can move wholesale money. The token was technically deployed on Monday, Oct. 19, according to CoinDesk’s report on the launch. JPM Coin represents dollar deposits held at JPMorgan; it is not a general-purpose stablecoin open to anyone to buy or hold.

The expansion moves the token from Base, Coinbase’s Ethereum layer-2 network, onto Ethereum itself. That gives institutions another network to use, while keeping access within JPMorgan’s institutional-client perimeter. The change matters because Ethereum already hosts a large ecosystem of tokenized assets and applications, but a public network also brings JPM Coin into a more open blockchain environment than the bank’s private Kinexys network.

What changes when JPM Coin is available on Ethereum?

Ethereum adds a route for JPMorgan clients to move the bank deposit token within the mainnet ecosystem, alongside the existing Base deployment. Kinexys Labs chief Emma Landriault said the move was intended to give institutional clients “multi-chain optionality” across web3 and traditional finance, in a statement reported by CoinDesk. The practical difference is access to another network, not a change in what the token represents: JPM Coin remains a claim linked to dollars deposited at the bank.

JPMorgan cited Ethereum’s liquidity and the presence of tokenized assets as reasons to add it. CoinDesk reported that nearly $50 billion in crypto assets was held in Ethereum-based applications, citing DeFiLlama. That depth may make the network useful for institutions settling trades or supporting tokenized assets, though it does not mean JPM Coin becomes freely transferable to every Ethereum user.

How does Ethereum compare with Base and Kinexys?

Base was JPM Coin’s first public-chain deployment, launched in November 2025. It is built on Ethereum technology but operates as a separate layer-2 network. Ethereum mainnet offers a different venue within the same broad ecosystem, while Kinexys remains JPMorgan’s private blockchain network. CoinDesk reported that Kinexys processes more than $7 billion in transactions daily; JPMorgan’s wider payments business handles about $12 trillion a day.

Those options involve trade-offs. Public networks connect the token to external blockchain activity and existing tokenized assets, while a private network gives the bank a more controlled operating environment. Base and Ethereum also differ in their network architecture. The expansion adds flexibility for clients, but it does not erase the need to meet JPMorgan’s eligibility requirements. Decrypt’s report says only vetted, approved counterparties can hold JPM Coin.

What should institutions watch next?

The next test is whether clients use Ethereum for real settlement activity, including payments, trades and collateral tied to tokenized assets. JPMorgan has also signalled plans to extend JPM Coin to the Canton Network, according to CoinDesk, which would add another network with a different design and audience. The bank’s multi-chain strategy will depend on whether institutions value access to public blockchain markets enough to operate across separate networks and their respective controls.

For now, Ethereum’s arrival is an expansion of JPM Coin’s reach, not a switch away from Base or Kinexys. Watch for further network launches, evidence of client activity and clearer details about how JPMorgan’s token moves between networks. Those will show whether multi-chain availability becomes useful infrastructure for institutional money or remains an option on paper.
