Upgrade Your Platform from Web2 to Web3
Web2 to Web3 Integration
Whether you're running a SaaS, marketplace, game, or mobile app — we help you integrate blockchain, crypto payments, NFTs, and decentralized identity (DID) into your existing Web2 product. Go from central to decentralized, without starting from scratch.
Transform Your Web2 Product into a Web3 Powerhouse
Tantrija enables your existing systems to support tokens, wallets, smart contracts, and decentralized storage — without disrupting your core business.

We bridge your current tech stack (React, Node.js, Firebase, PHP, etc.) with Web3 tools like MetaMask, smart contracts, IPFS, and token standards — allowing your platform to evolve, not rebuild.
Wallet Integration (MetaMask, WalletConnect, etc.)
Enable blockchain login and transactions using wallet providers like MetaMask, WalletConnect, Coinbase Wallet, and OKX Wallet. We add Web3 auth, session persistence, and wallet UX best practices to your Web2 interface.
Smart Contract Connection & Interaction
We connect your frontend/backend to smart contracts deployed on Ethereum, Polygon, Solana, and BNB Chain. Includes read/write functions, event listening, and transaction handling using ethers.js or web3.js.
NFT Integration into Web2 Platforms
Add NFT minting, display, transfers, or gated access to your platform. Ideal for marketplaces, games, loyalty programs, and content paywalls. Supports ERC-721 and ERC-1155 standards.
Token Payment Gateway Setup
Accept crypto payments with USDT, ETH, MATIC, or your custom token. We integrate payment flows using smart contracts, on-ramp/off-ramp services (Ramp, Transak, MoonPay), and secure transaction tracking.
Decentralized Identity (DID) & Web3 Auth
Implement decentralized login and identity management using protocols like ENS, Sign-In with Ethereum (SIWE), and Lens Protocol. Replace traditional logins with wallet-first experiences.
Off-Chain to On-Chain Data Sync
We build bridges between your Web2 databases (MongoDB, Firebase, PostgreSQL) and on-chain smart contracts. Sync assets, actions, and user data for hybrid Web2-Web3 models.
Web3 Storage Integration (IPFS, Arweave, Filecoin)
Store files, images, and metadata in decentralized storage. We handle pinning, access control, and CID-based referencing for permanent and censorship-resistant data.
Custom Dashboards for Web3 Ops
Build internal or customer-facing dashboards to monitor smart contract interactions, wallet stats, transaction history, NFT ownership, and token analytics — all pulled live from blockchain data.
