The blockchain promise. Delivered.

Understand what the EVM actually allows, verify every claim, and choose how you connect — without a single point of dependency.

A readable situation

On-chain status, detected capabilities, and proof sources brought together in one understandable flow.

CLI & local RPC

Controlled access

Scriptable inspection and a local HTTP endpoint routed through the RPC access points configured in Alter.

MCP for agents

Structured knowledge

Typed tools, verifiable results, and explicit limits that help an agent continue its task.

Vision & Commitment

Accessing the EVM should require neither a single dependency nor mandatory expertise.

🟡

A promise still unfinished

Decentralization, resilience, sovereignty.
That promise remains incomplete while access depends on one unavoidable interface or understanding the facts requires EVM expertise.

⚙️

Read. Prove. Act.

Alter connects intent to protocol reality.
Facts become readable knowledge, useful claims remain linked to evidence, and only genuinely available actions are presented.

📦

One intelligence, five surfaces

One shared source of truth.
Web, mobile, desktop, CLI, and MCP project the same knowledge to human users, technical operators, and software agents.

Alter keeps its results linked to observable on-chain facts through the RPC access points you choose.
You can cross-check the underlying information on Etherscan or GnosisScan.

From EVM history to accounting and tax language

Alter translates qualified assets and movements for the requested jurisdiction, then links every term to its evidence.

Qualify the asset

Coin, stablecoin, claim, debt, share, receipt, or collateral: Alter establishes the observable economic nature without assigning one universal treatment to a token.

Reconstruct the movements

One transaction may contain several movements. Alter reconstructs the history and qualifies acquisitions, disposals, payments, internal transfers, fees, loans, repayments, or income from the available facts.

Translate for the professional

Every term links to the on-chain evidence for the fact and to the regulatory or accounting source for the requested jurisdiction. If data or a source is missing, the translation remains undetermined.

Product boundary: Alter stops at the sourced translation of the history. It produces no final journal entry, tax calculation, regime selection, filing, or professional opinion. address.statement already provides the classified, proven foundation; jurisdictional translation and regulatory-source links still need broader coverage.

Five access surfaces, and what you can do on each

The same knowledge, expressed in the language and level of detail each interface needs.

Understand before you act

Alter turns on-chain facts into an understandable situation, with the proof source and the actions that are actually available. EVM vocabulary is not required to understand the result.

  • Visible evidence: Capability details show the on-chain source used by Alter.
  • Address situation: New, funded, active, and dormant states summarize the activity observed.
  • Verified history: Outgoing history imports show progress and verify transactions through RPC.

Local RPC endpoint & scriptable inspection

Work directly with JSON-RPC when needed, or use the domain objects Alter has already modeled.

  • Local RPC endpoint: alter rpc serve routes HTTP requests to configured endpoints with balancing, health monitoring, and failover.
  • Inspection with evidence: address inspect links detected capabilities to their on-chain source.
  • CLI automation: JSON and tree outputs fit into scripts and reproducible workflows.
Current scope: alter-cli · Alter Desktop · local HTTP endpoint, with no WebSocket or cloud/public service

alter-mcp · Server for AI agents

Structured, verifiable knowledge

Alter provides typed, discoverable MCP tools with results linked to evidence and explicit limits.

  • Verifiable portrait: address.inspect includes the proof source for each capability it exposes.
  • Complete result: address.concentration returns the full detected holder list.
  • Transaction context: transaction.inspect classifies every address involved in the transaction.
  • Classified statement: address.statement produces closed-period movements, wallet-perspective lines, reconciliations, and evidence for audit and control.
Available: alter-mcp. Not yet delivered: autonomous crypto purchase and end-to-end transactional autonomy.

Privacy by default

No tracking or analytics: requests use the RPC access points you configure, with no mandatory third-party database.

On-Chain Proof (you can verify yourself)

The facts behind a classification are readable directly on the public blockchain. Paste the address in Alter, then check on Etherscan or GnosisScan — you will see the same base information. Alter always distinguishes these on-chain proofs from the presentation heuristics that complement them.

Consistent surfaces

Web, Desktop, CLI, and MCP share one intelligence layer. Mobile apps remain forthcoming.
