Our Hedera Hashgraph Practice

ColdAI is a member of The Hashgraph Association and a delivery partner for enterprise teams building on Hedera. We design, build, and operate production systems on Hedera's hashgraph consensus — including tokenisation, stablecoins, programmable carbon, AI-agent payments, and permissioned enterprise networks via HashSphere.

Why Hedera, and why ColdAI

Hedera is a public, open-source distributed ledger built on the hashgraph consensus algorithm. It is governed by a council of global enterprises and operated as a permissionless network with predictable, USD-denominated fees, sub-second finality, and asynchronous Byzantine fault-tolerant (aBFT) security. For regulated institutions, that combination — a defensible consensus story, predictable economics, and protocol-level primitives for tokens, audit logs, and EVM smart contracts — is what makes production deployments realistic. ColdAI is a member of The Hashgraph Association and a delivery partner for enterprise teams building on Hedera. We design, build, and operate systems across the full Hedera stack: tokenisation, stablecoins, programmable carbon, AI-agent payments, and permissioned enterprise networks via HashSphere.

Our Hedera service lines

Eight focused practices spanning the Hedera stack

Hedera Token Service (HTS)

Native, protocol-level fungible and non-fungible tokens with KYC, freeze, supply, and royalty controls — no smart contract required.

Hedera Consensus Service (HCS)

Verifiable timestamps and fair ordering for audit trails, supply chains, AI receipts, and cross-chain messaging.

Smart Contract Service (HSCS)

EVM-equivalent Solidity contracts with native HTS and HCS system-contract integration.

Asset Tokenization Studio

Compliant security-token issuance for equity, debt, funds, and RWAs with on-chain transfer restrictions and lifecycle hooks.

Stablecoin Studio

Open-source SDK and admin platform for issuing and operating fiat-backed stablecoins on HTS.

AI Studio

Hedera Agent Kit and toolchain for AI agents that pay, settle, remember, and prove what they did on-chain.

Sustainability Studio (Guardian)

Tokenise and verify carbon credits, RECs, and biodiversity assets under Verra, Gold Standard, and ICVCM methodologies.

HashSphere

Permissioned, KYC-gated Hedera environment for banks, payment providers, and public-sector deployments.

How we engage on Hedera

A four-phase engagement model from architecture through operations

Architecture & Compliance Design

We map your use case, regulatory perimeter, and integration surface — then design the right mix of HTS, HCS, HSCS, and Studios to deliver it. Output: an implementation-ready architecture and compliance brief.

Build & Integrate

Engineering against Hedera SDKs (Java, JavaScript, Go) and Studios. We integrate KYC providers, custodians, banking rails, oracles, identity, and existing core systems.

Audit & Launch

Independent code review, key-management hardening, treasury and multi-sig setup, and mainnet rollout — including SOC2-aligned operating procedures.

Operate & Scale

Ongoing operations, monitoring, on-call, governance support, and feature delivery. Optional HashSphere managed environment for regulated workloads.

Where ColdAI typically delivers on Hedera

Use Case	Hedera Primitives	Typical Outcome
Tokenised deposits & branded stablecoins	Stablecoin Studio + HTS	Regulated, branded stablecoin live in 8–14 weeks
Real-world asset issuance (debt, equity, funds)	Asset Tokenization Studio + HSCS	Compliant primary issuance with on-chain registry
Carbon, REC, and biodiversity programmes	Guardian + HCS + HTS	Auditable, methodology-aligned environmental tokens
AI-agent commerce and machine-to-machine payments	AI Studio + HTS + HCS	Agents that transact, settle, and produce verifiable receipts
Permissioned enterprise DLT for regulated entities	HashSphere + HTS	KYC-gated network bridged to public Hedera mainnet
High-volume audit and supply-chain provenance	HCS	Cryptographically verifiable event log at protocol cost

Frequently asked questions

ColdAI is a member of The Hashgraph Association, the Swiss-based body that coordinates enterprise adoption and ecosystem grants for Hedera. We deliver Hedera engagements as an independent engineering and advisory firm.

Yes. We design and operate systems on public Hedera mainnet, on permissioned HashSphere environments, and across hybrid setups where private workloads bridge to public Hedera for settlement or anchoring.

Both. We deliver greenfield builds, but we also run ongoing operations — monitoring, on-call, treasury operations, governance support, and continued feature delivery — under retained engagements.

Hedera is our primary recommendation for regulated, high-throughput, predictable-cost use cases. We also work across Ethereum L1/L2s, Solana, Bitcoin, and permissioned ledgers where the use case warrants it. Our recommendations are technology-neutral.

Sub-Technologies

Hedera Token Service (HTS)

Native, protocol-level tokenisation on Hedera — issue fungible and non-fungible tokens without writing a smart contract. HTS supports KYC, freeze, pause, supply controls, custom fees, royalty fees, and atomic swaps, with predictable USD-denominated fees and sub-second finality. ColdAI implements HTS for digital assets, loyalty, real-world assets, and regulated securities.

Hedera Consensus Service (HCS)

A decentralised, verifiable ordering and timestamping service for any application that needs a trust-minimised log — supply-chain provenance, audit trails, market data, voting, AI-model receipts, and cross-chain messaging. HCS delivers fair ordering with sub-second finality at protocol cost. ColdAI uses HCS as the verifiable backbone for compliance evidence, agent telemetry, and high-volume audit pipelines.

Hedera Smart Contract Service (HSCS)

EVM-equivalent smart contracts on Hedera — deploy any Solidity contract, with first-class system-contract integration to HTS and HCS. Hedera's EVM gives you predictable gas costs, parallelised execution, and aBFT finality, while remaining tooling-compatible with Hardhat, Foundry, Remix, and Ethers.js. ColdAI builds DeFi, RWA, identity, and AI-agent contracts on HSCS.

Asset Tokenization Studio

Hedera's open-source toolkit for issuing compliant security tokens — equity, debt, funds, and real-world assets — with ERC-1400/3643-style transfer restrictions, partitions, controllers, snapshots, and lifecycle hooks built on HTS. ColdAI uses the Asset Tokenization Studio as the foundation for regulated issuances, integrating it with custodians, transfer agents, KYC providers, and on-chain registries.

Stablecoin Studio

Hedera's open-source SDK and admin platform for issuing and operating fiat-backed stablecoins on HTS — with KYC, freeze, mint and burn controls, multi-signature treasury operations, and proof-of-reserve hooks. ColdAI uses Stablecoin Studio to deliver branded, regulated stablecoins for banks, fintechs, payments providers, and tokenised-deposit programs.

AI Studio

Hedera's developer toolkit for AI agents that transact on-chain — covering identity, agent-to-agent payments, on-chain memory, tool calling, and audit trails. Built around the Hedera Agent Kit, AI Studio integrates with mainstream agent frameworks so autonomous systems can pay, settle, and prove what they did. ColdAI uses AI Studio to ship AI-agent commerce, machine-to-machine payments, and verifiable agent telemetry.

Sustainability Studio (Guardian)

Hedera's open-source Guardian platform for tokenising and tracking environmental assets — carbon credits, RECs, biodiversity credits, plastic credits — under Verra, Gold Standard, ICVCM, and other standard methodologies. Guardian uses policy workflows, schemas, decentralised identity, and HCS-anchored audit trails to make environmental claims verifiable end-to-end. ColdAI deploys and operates Guardian for issuers, registries, and corporate buyers.

HashSphere

HashSphere is Hedera's permissioned, enterprise-grade environment for regulated institutions — a managed Hedera network with KYC-gated access, customer-controlled stablecoin issuance, and seamless interoperability with the public Hedera mainnet. It gives banks, payment providers, and public-sector clients the operational, privacy, and compliance posture they need without giving up Hedera's economics or finality. ColdAI is a delivery partner for HashSphere deployments.
