Tether Funds Two Competing Chains to Repatriate Fees and Own Rail

Tether's stablecoin ecosystem is home to two competing chains, Plasma and Stable, each designed to address different aspects of the USDT economy. The move comes as a response to the $2.9 billion in annual network fees associated with USDT movement, which are largely captured by blockchains outside Tether's control.

Plasma is a full EVM Layer 1 chain that subsidizes its stablecoin lane through a paymaster contract, allowing for free USDT transfers and maintaining the familiar crypto economy intact. In contrast, Stable is a stripped payments rail where USDT itself serves as the gas token, with simple transfers exempt from fees by protocol rule.

Tether's decision to back both chains is seen as a strategic move to repatriate fees, own the rail, and design the user experience around the dollar. The issuer has already invested $373 million in Plasma through an oversubscribed sale, while Stable has attracted $2 billion in pre-deposits ahead of its mainnet launch on December 8.
