Rust smart contracts compiled to WebAssembly on a sharded, Secure Proof of Stake network, with ESDT tokens, dApps, and xPortal wallet integration delivered end to end.
MultiversX takes a different route to scale than most networks: instead of one global state, it splits state and execution across shards and rebalances them as the validator set changes. Transactions inside a shard settle in a single round; transactions across shards are handled asynchronously by the protocol. Contracts are written in Rust and compiled to WebAssembly, which gives you a strong type system and a mature toolchain rather than a bespoke contract language.
We build the full stack on MultiversX: smart contracts and their test suites, ESDT token issuance with the roles and properties set correctly, dApp front ends with wallet and xPortal integration, and the APIs and indexing behind them. Cross-shard behaviour and asynchronous calls get particular attention, because that is where MultiversX contracts most often behave in ways teams did not expect.

Contracts, tokens, and applications built for a sharded network.
Rust contracts compiled to WebAssembly using the official MultiversX framework, with tests written the way the framework expects.
Native token issuance on MultiversX, where fungible, semi-fungible, and non-fungible assets are all protocol-level primitives.
Application flows designed around asynchronous cross-shard execution instead of assuming everything settles atomically.
The application layer: front ends built on the MultiversX SDKs with the wallet options your users already have.
Staking, farming, and exchange mechanics implemented with the arithmetic care that financial contracts require.
The infrastructure behind a live dApp: API access, indexed data, and observer or validator nodes where you need them.
The contract framework, SDKs, and infrastructure behind a production MultiversX application.
The network, its SDKs, and the wallet most of its users hold.
Rust contracts compiled to WebAssembly, plus EVM interoperability where you need it.
dApps, wallet connections, and the APIs behind them.
Observer squads, devnet pipelines, and monitoring across all three shards.

The behaviours that catch teams out on a sharded, asynchronous network.
Callbacks, partial failures, and state that must not be assumed final until a cross-shard call actually returns.
Gas limits calculated for multi-step and cross-shard flows, so transactions do not fail halfway through a sequence.
Access control, reentrancy through async calls, and payment validation reviewed against the MultiversX execution model.
BigUint arithmetic and rounding directions checked explicitly, because financial rounding errors compound silently.
Storage layout versioning and upgrade procedures that preserve state rather than orphaning it.
Transaction status tracking through cross-shard settlement, so users see what actually happened rather than a spinner.
Where sharded throughput and native token primitives fit well.
Exchanges, liquid staking, and yield products built on native ESDT assets and low, predictable fees.
Protocol-level NFTs and SFTs with attributes and royalties, suited to in-game economies at volume.
Reward and membership products that reach a mainstream audience through the xPortal wallet.
Meta-ESDT instruments for structured products, real-world assets, and on-chain financial records.
From contract specification to a dApp live on mainnet.
We specify the contract set, storage layout, and token model, and decide which interactions cross shards, a decision that shapes both user experience and gas cost.
Rust contracts built in sprints with unit and blackbox scenario tests, running against a local testnet so behaviour can be inspected from the first weeks.
ESDT issuance with roles and properties configured correctly, plus SDK integration, wallet connection, and the dApp surfaces your users will touch.
Async flows tested including the unhappy paths, such as failed callbacks, out-of-gas mid-sequence, and partial state, because these are the cases that reach production untested.
Devnet and testnet deployment with real wallets, external audit where value at risk warrants it, remediation, and a staged mainnet release.
API and indexer monitoring, transaction failure alerting, and contract upgrades as the product develops.
What teams ask before building on MultiversX.
The network splits state and execution across shards and adjusts the number of shards as the validator set changes, which is how it scales throughput. In practice it means transactions within a shard settle in one round, while transactions between shards are executed asynchronously by the protocol. Your application has to account for that: a cross-shard call is not atomic, and a contract cannot assume the result of one is available immediately. We design contract placement and call flows around it rather than discovering it during testing.
MultiversX contracts compile to WebAssembly, and Rust is the language its official framework targets. That brings a strong type system, real tooling, and a large ecosystem of libraries, and it removes several classes of bug that bespoke contract languages leave open. The framework also provides a scenario testing system that lets us exercise contract behaviour, including cross-shard flows, before anything is deployed.
ESDT tokens are issued and tracked by the protocol itself rather than by a contract you deploy and maintain. Balances live in the account state, transfers are native operations, and fungible, semi-fungible, and non-fungible variants are all built in. That means no token contract to audit, consistent behaviour across every wallet and dApp, and lower gas, but issuance, roles, and properties have to be configured correctly at creation, which is where mistakes usually happen.
The logic ports; the code does not. Contracts have to be rewritten in Rust, and the parts that assume atomic composability with other contracts need reworking for the asynchronous cross-shard model. We normally start with a functional specification derived from the existing contract, then design the MultiversX implementation against that rather than translating line by line, which produces safer results.
Most MultiversX users hold xPortal, the ecosystem’s mobile wallet, and it is the smoothest path for consumer applications. We also integrate the Web Wallet, browser extension, and Ledger hardware wallets, so institutional and power users have appropriate options. The sdk-dapp libraries handle the connection layer for all of them behind a single integration.
A token launch with a supporting contract and a simple dApp is typically 6 to 10 weeks. A full DeFi or gaming platform with multiple contracts, cross-shard flows, indexing, and an audit usually runs 4 to 7 months. We deliver working contracts on devnet early so the model can be validated before the full build is committed.
We work across the major layer 1 ecosystems, not just one.
