Agent economy glossary

Every term in the agent payment infrastructure, agentic commerce, and AI-native finance ecosystem — defined precisely, with examples, and cross-referenced.

Agentic commerceCore concept

The emerging category of commercial transactions initiated, negotiated, and completed by AI agents on behalf of humans or other systems, without human approval at each step. Projected to represent 9% of all US online purchases by 2030 ($261 billion).

Example: An AI agent autonomously purchases data from a vendor API, pays the invoice, and logs the transaction — all while the human operator sleeps.
Agent economyCore concept

The emerging economic layer in which AI agents participate as independent economic actors — not just tools assisting humans, but participants that earn, spend, negotiate, and operate on their own financial behalf.

Example: An orchestrator agent hires specialized sub-agents for research, writing, and review — paying each upon task completion from its own wallet.
Agent payment infrastructureCore concept

The class of financial technology designed from first principles for AI agents as the primary economic actor. Provides agent-owned wallets with programmatic identity, autonomous transaction authorization without human sign-off, and on-chain settlement with machine-readable audit trails.

Example: BananaCrystal provides agent payment infrastructure through a single MCP endpoint — 10 tools, 150+ currencies, Hedera settlement in under 5 seconds.
Agent walletCore concept

A non-custodial financial account owned and operated by an AI agent, not a human. Identity derives from the agent's programmatic ID. The wallet holds a balance, has an on-chain address, and can send and receive value autonomously.

Example: wallet = client.wallets.create(agent_id='my-trading-agent', currency='USDC', spending_limit=500)
API key scopeTechnical

An explicit permission level assigned to a BananaCrystal API key that controls what operations an agent can perform. Available scopes: read_only, transfer, swap, fiat, kyc.

Example: A read-only research agent gets a read_only key. A treasury bot gets transfer and swap scopes.
Autonomous authorizationCore concept

The mechanism by which an AI agent authorizes transactions programmatically, without requiring human approval per transaction. Enabled by spending policy set in advance by the operator.

Example: Agent calls transfer_tokens() — policy engine validates limits and allowlists — transaction executes without human involvement.
Autonomous paymentsCore concept

Transactions initiated, authorized, and settled entirely by machines — with no human in the approval loop at any stage. The core primitive of the agent economy.

Example: An agent calls transfer_tokens(amount=12.50, to='vendor:api-service-7g2'). The payment settles in 3.2 seconds with no human involvement.
FinalityTechnical

The point at which a blockchain transaction is considered irreversible and complete. Hedera offers absolute finality in under 5 seconds — a transaction is either settled or rejected with certainty, no ambiguity.

Example: BananaCrystal returns a confirmed settlement in 3–5 seconds on Hedera with absolute finality.
HederaTechnical

The enterprise-grade public distributed ledger network that BananaCrystal uses for transaction settlement. Key properties: absolute finality in 3–5 seconds, $0.001 average transaction fee, carbon-negative network, 10,000+ transactions per second throughput.

Example: BananaCrystal settles all stablecoin transfers on Hedera. Transaction hash format: '0.0.789@1711234567'
IdempotencyTechnical

The property of an operation that produces the same result whether executed once or multiple times. Critical for agent payment infrastructure — if an agent retries a failed request, the payment must not be processed twice.

Example: BananaCrystal enforces idempotency via unique transaction references. Duplicate requests within 24 hours are rejected with a 409 Conflict response.
MCP (Model Context Protocol)Protocol

An open standard introduced by Anthropic in November 2024 that enables AI agents to securely connect to external systems through a standardized interface. Think of it as HTTP for AI agents.

Example: An agent connects to BananaCrystal MCP server with one config line and discovers 10 payment tools automatically via the MCP manifest.
Multi-agent payrollCore concept

A payment pattern in which an orchestrator agent pays sub-agents for completed work — creating an autonomous economic system where agents earn and spend without human involvement.

Example: An orchestrator agent verifies that a research sub-agent delivered its output, then calls transfer_tokens() to pay it $2.50 in USDb.
Spending limitsTechnical

Operator-configured caps on agent spending enforced at the infrastructure level. Types: per-transaction maximum, daily rolling cap, monthly cap, and recipient allowlists.

Example: wallet = client.wallets.create(spending_limit=500, max_tx_amount=50) — agent cannot exceed $50/tx or $500/day regardless of LLM decisions.
StablecoinFinance

A cryptocurrency designed to maintain a stable value relative to a reference asset (typically a fiat currency). USDb is BananaCrystal's USD-pegged stablecoin on Hedera. 150+ local currency stablecoins are available.

Example: An agent swaps 100 USDb to NGNb (Nigerian Naira stablecoin) to pay a vendor in Nigeria — settling in 4 seconds at $0.001 fee.
USDbFinance

BananaCrystal's USD-pegged stablecoin on the Hedera network. 1 USDb = 1 USD. Used as the primary settlement currency for agent payments. Backed 1:1 by USD reserves.

Example: transfer_tokens(amount=25, token='USDb', to='0.0.654321') — sends $25 to the recipient's Hedera wallet.
