Wormhole
introduces
the
Native
Token
Transfers
(NTT)
framework,
offering
a
flexible,
open-source
solution
for
transferring
tokens
across
blockchains,
ensuring
security
and
composability.

Wormhole
has
announced
the
launch
of
its
Native
Token
Transfers
(NTT)
framework,
designed
to
facilitate
seamless
and
secure
token
transfers
across
multiple
blockchains.
This
innovative,
open-source
solution
aims
to
provide
integrators
with
full
control
over
token
behavior
on
each
chain,
including
aspects
such
as
token
standards,
metadata,
ownership,
and
custom
features,
while
maintaining
a
unified
supply.

Key
Features
of
NTT

The
NTT
framework
stands
out
due
to
several
key
features:

Unified
User
Experience

NTT
ensures
tokens
retain
their
properties
across
all
chains,
providing
a
consistent
and
fungible
user
experience.

No
Liquidity
Pools
Required

Tokens
can
be
transferred
without
the
need
for
liquidity
pools,
thereby
avoiding
associated
fees,
slippage,
and
MEV
risks.

Integrator
Flexibility

Integrators
have
full
ownership
and
upgrade
authority
over
token
contracts,
offering
extensive
customizability.

Advanced
Rate
Limiting

Configurable
rate
limits
for
inbound
and
outbound
transfers
help
prevent
abuse
and
manage
network
congestion.

Global
Accountant

This
feature
ensures
accounting
integrity
by
verifying
that
the
number
of
tokens
burned
and
transferred
out
of
a
chain
does
not
exceed
the
number
minted.

Access
Control

Protocols
can
assign
administrative
functions
to
different
addresses
to
enhance
security
and
respond
quickly
to
potential
risks.

Maximum
Composability

The
open-source
nature
of
NTT
promotes
widespread
integration
with
other
protocols.

Industry-leading
Security

NTT
is
secured
by
Wormhole’s
Guardian
Network,
consisting
of
19
reputable
validator
companies
that
verify
cross-chain
messages.

Custom
Attestations

NTT
supports
external
verifiers
and
custom
message
attestation
thresholds
for
enhanced
security.

NTT
vs.
Token
Bridges

While
Wormhole’s
existing
cross-chain
messaging
protocol
enables
bridging
applications,
NTT
offers
significant
advantages
over
traditional
token
bridges.

Token
Bridge

• 
  Mechanism:
  Lock
  and
  mint
  model.
• 
  Security:
  Preconfigured
  rate
  limiting
  and
  integrated
  Global
  Accountant.
• 
  Contract
  Ownership:
  Upgradeable
  via
  Wormhole
  Governance.
• 
  Integration:
  Straightforward
  and
  permissionless
  deployment
  on
  multiple
  chains.

Native
Token
Transfers

• 
  Mechanism:
  Burn
  and
  mint
  mechanism
  or
  hub
  and
  spoke
  model.
• 
  Security:
  Configurable
  rate
  limiting,
  pausing,
  access
  control,
  and
  threshold
  attestations.
• 
  Contract
  Ownership:
  Integrators
  retain
  ownership
  and
  upgrade
  authority.
• 
  Integration:
  Customizable
  framework
  for
  bespoke
  deployments.

NTT’s
flexibility
and
control
make
it
ideal
for
sophisticated
multichain
token
deployments.

Core
Components
of
NTT

The
NTT
framework
consists
of
two
main
components:
Managers
and
Transceivers.

Managers

Managers
handle
rate
limiting,
message
attestation,
and
token
transfers.
Key
functions
include:

• 
  transfer:
  Initiates
  the
  token
  transfer
  process.
• 
  quoteDeliveryPrice:
  Quotes
  the
  fee
  for
  delivering
  a
  message
  to
  a
  target
  chain.
• 
  registerPeer:
  Establishes
  trust
  between
  NTT
  manager
  contracts
  across
  chains.

Transceivers

Transceivers
facilitate
NTT
transfers,
encoding,
sending,
receiving,
and
decoding
messages
across
chains.
They
support
various
backend
verification
mechanisms.
Key
functions
include:

• 
  sendMessage:
  Sends
  messages
  to
  a
  specified
  recipient
  chain.
• 
  quoteDeliveryPrice:
  Estimates
  the
  cost
  of
  delivering
  a
  message
  to
  a
  target
  chain.

NTT
Security

NTT
offers
full
customization
across
its
security
stack,
supporting
both
burn-and-mint
and
hub-and-spoke
models
for
cross-chain
supply
management.
Configurable
per-chain
rate
limits
manage
transfer
volumes,
with
excess
transfers
queued
and
released
after
rate
limits
expire.

Access
control
features
allow
for
distinct
roles
such
as
Owner
and
Pauser,
enhancing
security
by
enabling
quick
responses
to
potential
risks.

The
Global
Accountant
ensures
integrity
by
performing
checks
on
every
token
transfer,
enforced
by
Wormhole
Guardians.

Integrating
with
NTT

Wormhole’s
NTT
framework
offers
a
comprehensive
and
flexible
solution
for
secure,
efficient,
and
customizable
token
transfers
across
blockchains.
Integrators
can
implement
governance
mechanisms
to
manage
transceivers
and
upgrade
contracts,
ensuring
security
and
adaptability.

Custom
message
verification
can
be
protocol-specific
or
provided
by
third-party
attesters,
enhancing
transaction
integrity.
