Benefits
A smart contract encodes the terms of an agreement and executes them automatically once conditions are met. No manual settlement, no intermediary: the blockchain network itself validates and enforces the terms, so counterparties transact without waiting on a third party to sign off.
Contract logic is enforced by the network, not by a single server. Predefined rules written into the smart contract govern how the dApp behaves, and every state change is validated across a peer-to-peer network, which sharply limits the surface for tampering, intrusion, or fraud.
Participants transact under wallet addresses rather than legal names. A sender can move funds across borders without exposing their identity, while the transaction itself remains traceable on-chain, giving users privacy and the ledger a permanent, auditable record.
Why Webisoft
Webisoft's blockchain engineers have shipped token contracts, open-source DeFi wallets, and protocol integrations across multiple chains. That experience feeds directly into your DeFi development: we know where token designs break, which standards to extend, and how to keep upgrade paths open in a fast-moving space. We run timeboxed iterations with daily standups and sprint planning, so scope, estimates, and progress stay visible, without compromising clean code or your requirements.
Ethereum, Ethereum Layer 2, Polygon, CosmWasm, Solidity, Rust, Web3.js, and Python
Our core blockchain team designs interoperable systems: multiple DeFi protocols integrated into a single module, with clean interfaces between chains and services.

FAQ
Real world assets
Real world asset tokenization is mostly legal and operational engineering with a smart contract at the center. We build the issuance, compliance, custody integration, and data layers that let an off-chain asset be held, transferred, and redeemed as a token, working alongside your legal counsel, custodian, and transfer agent. Token design starts from the asset, so that is where we start.
Whole properties, or shares in the legal entity that owns them, issued as fractional tokens. Typical contract work covers investor allowlists, rental income distribution in stablecoins, and transfer rules that mirror the entity's shareholder register.
Fungible tokens representing units of a fund or special purpose vehicle that holds the securities. The contracts handle subscriptions, redemptions, yield accrual or distribution, and net asset value updates fed by an oracle or by the fund administrator.
Pools of receivables or loans tokenized so lenders can fund them on-chain. The work centers on pool accounting, repayment priority, and the reporting investors need to see what backs each pool.
Tokens backed one to one by allocated physical reserves, such as gold held in a vault. Minting and burning are tied to custodian attestations, and proof of reserve feeds let holders check the backing themselves.
Unique items held by a custodian and paired with an ERC-721 token that represents the redeemable claim. The redemption flow burns the token when the physical item leaves the vault.
Contractual assets such as company shares, royalty streams, and licensing rights. Because they are already defined by contract, their rules map cleanly into token logic, with distributions paid to holders on-chain.
Issuance flow
We start with the asset, the jurisdictions you will sell into, and the investor profile: retail, accredited, or institutional. Your counsel and the originator confirm title, encumbrances, and the valuation source. We turn those answers into token requirements before any chain is chosen.
Most issuances hold the asset in a special purpose vehicle so it stays insulated from the platform's creditors, and most tokens that represent real world assets are treated as securities. Your legal counsel decides the structure and the classification. We translate them into contract behavior: who may hold the token, how it transfers, and what it entitles the holder to.
ERC-20 for fungible fractional units, ERC-721 for unique assets, and permissioned standards such as ERC-3643 or ERC-1400 when transfers must be limited to verified wallets. Regulated offerings usually take the permissioned route, because the contract checks eligibility on every transfer.
We connect your KYC and AML provider to an on-chain allowlist, encode holding rules by jurisdiction, and build the issuer controls regulators expect, such as freezing an address or recovering tokens for a verified holder who loses a wallet.
The custodian or trustee, the oracle network, and your transfer agent or fund administrator are integrated so on-chain balances, valuations, and reserves stay in sync with off-chain records.
Contracts go through an independent security audit, which we coordinate, before minting. After issuance we maintain the contracts and the integrations behind distributions, redemptions, and corporate actions for the life of the token.
Implementation decisions
The smart contract is rarely what breaks an RWA product. These are the decisions we settle with you early, because they shape everything built after them. We provide the engineering, not legal advice: your counsel owns the legal conclusions.
Rules differ sharply by market. In the United States, most asset-backed tokens are treated as securities. In the EU, MiCA covers crypto assets, while tokens that behave like financial instruments fall under MiFID II. Canada, Singapore, and the UAE each apply their own securities and licensing frameworks. We design transfer rules so one contract can enforce different eligibility rules per jurisdiction.
An SPV, trust, or fund structure gives token holders a defined claim and protection if the platform fails. Offering documents should state exactly what the token entitles a holder to: ownership, a share of income, a redemption right, or something narrower. The contract should never promise more than the documents do.
A regulated custodian or trustee holds the underlying asset. On the token side, issuer admin keys sit behind multisignature or MPC custody with separated roles, and investors either use institutional custody providers such as Fireblocks or Anchorage or hold tokens in their own allowlisted wallets.
Prices, net asset values, and proof of reserve data reach the chain through oracle networks such as Chainlink or through signed attestations from the custodian or administrator. Contracts check how fresh the data is and pause sensitive actions when a feed goes stale. Assets without a live market price, such as property, rely on periodic appraisals published on-chain.
Ethereum and Layer 2 networks such as Polygon and Arbitrum offer the deepest tooling and ERC-3643 support. Polymesh builds identity and compliance into the protocol. Stellar suits payment-linked assets, and Avalanche subnets allow jurisdiction-specific networks. Existing platforms such as Centrifuge package much of the stack. We choose by investor location, permissioning needs, and the cost of lifecycle events at your expected volume.
Lockups, redemption windows, notice periods, and secondary transfers between eligible holders are encoded in the contract and matched to the offering documents, so exit mechanics work as described from day one.
