AI Agent Development for Blockchain

We build AI agents for defined blockchain workloads, including onchain monitoring, transaction drafting, treasury operations and reconciliation. Agents operate within defined permissions and spending limits, with human approval for value-moving actions. We use approved frontier and private models under a data policy agreed with your team.

How it works

  1. 1

    Identify the workload

    We look for repetitive judgment calls with clear inputs. Where ordinary software fits better, we say so.

  2. 2

    Define the authority boundary

    We agree what the agent can do autonomously, what requires human approval and what remains off-limits.

  3. 3

    Design tools and guardrails

    We set least-privilege access, spending limits and allowlisted contracts, and keep signing outside the model.

  4. 4

    Build the evaluation set first

    We write representative tasks with expected outcomes and known failure cases. That becomes the acceptance bar.

  5. 5

    Build in loops and attack it

    You see weekly demos. We test for prompt injection, data leakage and unsafe transactions.

  6. 6

    Increase autonomy in stages

    The agent runs in a sandbox, then shadow mode, then approval-required, then alone. Each stage needs evidence.

  7. 7

    Monitor after launch

    We keep the evaluations running as models and data change. A named owner holds the audit trail.

Frequently asked questions

What can an AI agent do in a blockchain context?
Typical workloads include monitoring onchain activity and raising alerts, drafting and simulating transactions for human approval, managing routine treasury or position operations within strict limits, triaging support and governance discussions, summarizing proposals, reconciling onchain and off-chain records, and operating research or data pipelines. LimeChain scopes agents around bounded, observable workflows rather than open-ended autonomy over assets.
How do you stop an agent doing something harmful onchain?
Through layered controls rather than prompt instructions. LimeChain enforces least-privilege tool access, spending and rate limits, allowlisted contracts and destinations, mandatory transaction simulation before signing, human approval gates for high-impact actions, separated signing authority so the agent cannot reach keys directly, and a full audit trail. Autonomy expands only after evidence from the shadow and approval-required stages supports it.
How do you evaluate whether an agent is good enough?
LimeChain builds an evaluation set of representative tasks, expected outcomes and known failure examples before broad implementation, then measures task success, groundedness, tool-call correctness, unsafe action rate, latency, cost and regression against that baseline. Because models, data and downstream systems change, those evaluations keep running after launch rather than acting as a one-time acceptance test.
What about prompt injection?
Prompt injection is treated as a standing threat rather than a solved problem, particularly where an agent reads untrusted content such as web pages, onchain data, documents or user messages. LimeChain tests injection paths explicitly, separates untrusted content from instructions, restricts what the agent can do with retrieved content, keeps high-impact actions behind deterministic checks or human approval, and monitors for anomalous tool use in production.
Which models does LimeChain use, and where does our data go?
LimeChain combines approved frontier models with private LimeChain models running on LimeChain-controlled hardware, and the model and data policy is agreed during scoping. Sensitive project context and core intellectual property can remain inside the private environment, and private-only delivery is available where required.
Should this be an agent or normal software?
Often it should be normal software, and LimeChain says so when that is the case. Agents earn their cost where the input is unstructured, the path varies between cases and judgment is genuinely required. Where the process is deterministic, an agent adds latency, cost, non-determinism and a new attack surface for no benefit. That assessment is the first step of the engagement.
