Sui Tops $1T in Stablecoins; Mysten Plans Zero-Fee Payments

Sui has processed more than $1 trillion in stablecoin volume since August, founder Adeniyi Abiodun said at Consensus 2026. Mysten Labs plans to support zero-fee, private stablecoin transfers on the Sui blockchain and is testing post-quantum signature technology.

Abiodun described Sui as the “default network for how you move money.” He said Mysten’s goal is to remove fees for stablecoin transfers and to provide greater privacy for users. He cited a $100 cross-border transfer to Nigeria that carried $35 in fees as an example of current payment costs and warned consumers should not accept a reality where “bank accounts look like Twitter.”

Drawing on his prior work at Facebook, Abiodun noted that automated systems already drive more than 80% of internet traffic and predicted money movement would shift to agent-driven workflows. He added that users “should not be able to tell agents from humans onchain.”

Mysten is testing a storage layer that can bundle encrypted intent with transactions. Abiodun said the capability could support chargebacks and fraud-resolution mechanisms if automated agents act incorrectly.

The network is trialing post-quantum signatures on its testnet, aiming for a rollout before anticipated EU mandates on quantum-resistant cryptography in 2030. Abiodun offered to open-source Mysten’s quantum research and to coordinate with the Bitcoin ecosystem on the issue.

Developer activity on Sui increased about 200%, Abiodun reported, which he attributes to features such as onchain market-making and atomic multi-transaction submits. The mainnet has experienced outages: a January 2026 consensus-processing divergence stalled the network for hours, and a November 2024 bug in transaction scheduling caused a roughly three-hour validator crash loop.

Abiodun cited price data showing the native token SUI trading near $0.99, down about 3% over 24 hours and roughly 81% below its all-time high of $5.35 set in January 2025.

Mysten’s stated roadmap lists zero-fee stablecoin sends, private payments, encrypted intent storage and post-quantum signatures as planned features to support payments, agent-driven finance and onchain dispute resolution.
