Sentre Protocol

Sentre Protocol is an all-in-one open platform on Solana that combines a decentralized application store, an automated market maker, and a developer SDK — designed to give both DeFi users and early-stage builders a shared foundation for liquidity, tooling, and distribution.

How It Works

Sentre's architecture has three interlocking layers: SenOS (the operating system), SenHub (the developer platform), and SenSwap (the liquidity engine). These components are bound together by the [[TOKEN:SENBBKVCM7homnf5RX9zqpf1GFe935hnbU4uVzY1Y6M]] (SNTR) token, which serves as a universal bridge across all pools and grants governance rights over the ecosystem.

SenOS functions as a shared runtime environment where users aggregate third-party DApps into a customizable dashboard. Developers deploy applications through GitHub and GitHub Pages; the platform uses module federation so each DApp runs as a micro-frontend while drawing on shared state management (React + Redux) and a consistent UI system based on Ant Design. All DApps inherit platform-level wallet connectivity, token account data, and liquidity access from day one.

SenHub is the developer-facing layer. It provides a create-senhub-app CLI, pre-built smart contract frameworks for Solana, off-chain libraries for blockchain communication, and a visual sandbox for testing across mainnet, testnet, and devnet. Developers pay no fees to use Sentre's services or liquidity.

SenSwap is the protocol's AMM and liquidity accumulator. It runs two pool types:

• Dual-token pools: Traditional two-asset pairs using the constant-product formula, suited for non-correlated and exotic assets.
• Triad-token pools: Three-asset pools with SNTR as the mandatory middle token. These enable asymmetric (one-sided) deposits via a mechanism called Simulated Single Exposure — the protocol automatically calculates and simulates the balancing swap, so a user depositing a single token does not need to hold or manage the pairing asset. SNTR as the universal bridge also reduces trade hops and lowers slippage across the ecosystem.

The AMM applies an Adaptive Fee Model that scales fees with price volatility rather than charging a flat rate. Larger price movements trigger higher fees, which mathematically reduce the impermanent loss that liquidity providers face. A fixed 0.05% protocol fee on top of the adaptive rate flows into ecosystem development and a buyback mechanism that converts accumulated fees into SNTR and distributes them to platform services.

Liquidity providers receive LP tokens they can stake in Sentre's farming contracts to earn additional SNTR rewards. The Sen Booster module lets users lock LP tokens for 7 to 90 days in exchange for profit boosts of up to 140% SNTR.

Key Products

• SenSwap: AMM with adaptive fees, asymmetric deposits, triad-token pools, and DAO governance controls over which projects can access protocol liquidity.
• SenHub / SenOS: Developer SDK and DApp store for launching, testing, and distributing Solana applications with shared infrastructure.
• Sen Store: The DApp marketplace where verified projects become native ecosystem members rather than external integrations.
• Token Distribution Tools: Bulk sender, airdrop, and vesting utilities for project token launches.
• Launchpad: Tooling for new project launches.

Token

The native token was originally launched as SEN and later renamed to SNTR to reduce market confusion with other protocols. SNTR has a fixed total supply of 1 billion tokens, with approximately 999.94 million in circulation as of mid-2026.

SNTR's on-chain mint address is SENBBKVCM7homnf5RX9zqpf1GFe935hnbU4uVzY1Y6M on Solana.

Token functions include:

• Governance: SNTR holders vote on which new projects gain access to SenSwap liquidity.
• Fee reduction: Routing swaps through SNTR reduces the effective fee from approximately 0.3% to 0.25%.
• Liquidity bridge: SNTR appears in all triad pools, enabling one-token-to-any-token routing.
• Staking and farming: Earn protocol revenue and LP rewards.

The token launched via a two-phase fair launch on December 17, 2021. Phase one was an open sale where participants deposited USDC and the final price was determined by dividing total vault funds by the number of SEN tokens sold. Phase two offered a 24-hour grace period for optional USDC withdrawal. Retroactive rewards of 2 million SEN were distributed to early liquidity providers (1M), launch participants (600K), and traders (400K). The token reached an all-time high of approximately $0.056 on January 7, 2022. As of mid-2026 the token trades at a fraction of that level, with near-zero reported liquidity and volume.

Security and Audits

CertiK assigned Sentre a security score of 3.1. Smart contracts are open-source on GitHub under the DescartesNetwork organization. The platform applies community governance for DApp verification — projects must pass a vote before gaining access to SenSwap liquidity — but detailed third-party audit reports have not been prominently published by the team.

Team and History

Sentre was founded by Tu Phan, who won second prize in Solana's inaugural hackathon in 2020. The core team comprised four technical professionals with backgrounds at Infinity Blockchain Labs and Binance, each with five or more years of industry experience. The protocol launched on Solana mainnet in December 2021, and SenHub Version 2.0 followed on January 7, 2022, adding a drag-and-drop interface, light/dark themes, and a development sandbox. The project later formed a partnership with Superteam Vietnam to expand developer adoption in Southeast Asia.

The documentation site labels itself "Sentre Legacy," and social channels show minimal recent activity, suggesting that while the website and documentation remain accessible, the protocol's active development and community engagement have significantly wound down from their 2021-2022 peak.

Solana Ecosystem Fit

Sentre targeted a niche that has since been addressed by more established Solana DeFi protocols: it sought to combine AMM liquidity (comparable to Orca or Raydium) with a developer platform, all under one token. Its listed ecosystem partners at launch included Solana Foundation, Superteam Vietnam, Orca, Raydium, Phantom, and Solend. The adaptive fee model and asymmetric deposit mechanism were technically differentiated ideas that anticipated later industry directions, though Sentre did not achieve the scale needed to become a durable liquidity hub.
