• Listed as an on-chain infrastructure partner on SDP, the platform used by Mastercard, Worldpay, and Western Union
• The first Korean company to join the Solana institutional infrastructure used by global payment and financial firms — expanding on-chain settlement infrastructure options for Korea's financial sector

SEOUL, October 1, 2026 — Lambda256, a blockchain company and subsidiary of Dunamu, announced on October 1 that its infrastructure platform, Nodit, has joined the Solana Foundation's institutional platform, the Solana Developer Platform (SDP), as an on-chain infrastructure partner. Nodit's participation was announced at Solana Summit Korea, held on September 30.

SDP is a platform the Solana Foundation provides for financial institutions and enterprises, offering token issuance, custody, payments, RPC, and compliance functions through a single dashboard and API. More than 30 infrastructure partners are pre-integrated across four areas — node/RPC, institutional custody, compliance, and on/off-ramp — allowing institutions to develop Solana-based financial services without separately contracting and integrating with multiple providers. Mastercard, Worldpay, and Western Union are among its early users. Until now, node/RPC partners had consisted of US- and Europe-based companies; Nodit is the first Asian infrastructure company to join this area.

Nodit provides a Node API supporting mainnet and devnet RPC on the Solana network, a large-scale on-chain data service (DataShare), and validator operation services. It entered the validator service business in November 2025, and in February 2026 became the first in Asia to integrate a node with DoubleZero, a high-performance network for Solana nodes.

Nodit's node infrastructure is operated on a redundant dual-IDC architecture, and major Korean exchanges including Upbit, Coinone, and DigitalX use Nodit. Lambda256 also conducted digital asset proof-of-concept (PoC) projects this year with KSNET and the Credit Finance Association, among others.

Michael Cho , CBO of Lambda256, said, "For financial institutions to operate payment and settlement services on a public blockchain, they need node infrastructure that combines large-scale traffic handling, data integrity, and a robust failure-response system." He added, "Based on the operational experience we have accumulated with major Korean exchanges and financial-sector PoCs, Nodit will support the stable operations of domestic and global financial institutions adopting Solana-based services through SDP."

Nodit is the enterprise on-chain infrastructure platform operated by Lambda256. It is the first Korean blockchain technology company to obtain SOC 2 Type I and Type II certification, and it processes an average of more than 400 million transactions daily across 70+ blockchain networks. Lambda256 supports financial institutions' adoption and operation of digital assets through Nodit.
